Title: So you want to build a computer...
Post by: Perd Hapley on April 26, 2009, 12:28:23 AM
Those of you who've answered my flurry of computer questions lately have some idea of my technical geek-competency - or lack thereof.  Should I even think about rolling my own?  How hard is it? 

This is a long-term project; I expect to put it together sometime in the next two years.  I might start salting away parts right now.  I'll be looking for used parts, where I can get away with it.  Any tips?  I've seen some books on the subject.  Any recommendations on those?

I'm not looking for anything spectacular or specialized.  The most demanding thing it will have to do is run video from the web or DVD, or run multiple Word documents and Firefox tabs.  I'll probably use Ubuntu on it, but I might want to add Windows 7, or whatever they're going to call it. 

And I'm well aware that I could buy a real neato computer right now, at Geeks.com, and probably save myself a lot of time, money and aggravation.  But I really just want to do it, just to do it.   

For processors, should I look for an AMD or an Intel, or what?  If I use, say, a P4 HT, at 3 GigHz, will I be sorry I didn't hold out for a Dual-Core?

Will a 250 Watt power supply work alright, or does it have to be a 450 Watt, or something?  I'm thinking about using the case/power supply from a Dell GX240.  They have a 250 Watt supply. 

What about motherboards?  Is DDR 1 good enough, or will I be sorry I didn't go for the DDR2? 

If I use an older CD drive, will it be problematical, or is one as good as the other? 

Thanks,

Josh

I like AMD. They are always cheaper per performance point. I have a dual-core 5400 I believe.

Most people go overkill on PSU by a lot. Then again cheap PSUs are often underrated. A GOOD (seasonic) 300W psu is enough for the great majority of normal (ie not dual video card etc.) systems.

DDR is a waste of time. DDR2 all the way, this isn't 2004.

As long as the CD drive works, it works. Some are faster and quieter than others.

Right now, get Nvidia graphics if you want to run linux.

There are several guides on the internet that detail how to build a computer.  A little googling should yield a good one.


Most motherboards these days are going to be DDR2.  Unless you buy a used one, going with DDR2 would be easier, and it probably won't cost you that much extra money.

Newegg.com always has some good deals on CPU/motherboard combos (http://www.newegg.com/Store/ComboDeals.aspx?ComboStoreID=1&name=CPUs-Motherboards).  I'd check there if you are planning on buying new.  You will NOT find a P4 motherboard for a decent price.  It's too obsolete, and anything you do find will likely not be very capable and will cost far more than newer ones will.  I found this out several years ago when my P4 board fried.

Get a decent AMD processor in the $50-100 range; it will serve you well.  I bought an AMD 64 3800+ two years ago for $55 or so, and with graphics cards upgrades, I can still play most modern games.

If you get a new motherboard/cpu, it's not likely your Dell power supply will be compatible, particularly if the new board has an AMD processor. Also, I've learned the hard way that it's not a good idea to skimp on power supplies. While some cheap power supplies are ok, the vast majority are not to be trusted.  I had to rebuild twice due to cheap power supplies - a crappy power supply can fry your motherboard or destroy your video card.  Another problem with cheap power supplies is that their true rated power doesn't come close to what the manufacturers claim it to be. 

Seasonic psu's are ok.  Corsair makes some of the best ones for the price, though, however they are a bit spendy (my 450 watt Corsair was in the $80 range when I bought it a year or two ago).  Newegg currently sells a Corsair 400 watt model (http://www.newegg.com/Product/Product.aspx?Item=N82E16817139008) for $50 that would probably work extremely well for your purpose.

Incidentally, Corsair also makes some really good memory, as well, and their value DDR2 RAM is usually very well priced.

Like Zahc said, if the CD drive works, it works.  You may want to look into something that can play and burn DVDs and CDs, though, if your current model can't.  They're more convenient.

I've had good results with Antec power supplies and cases, fistful.  Look at some of the user reviews on Newegg before you make a purchase.  They are very helpful.

I've had bad luck with Antec. I had a 550 watt antec PS die and my brother had a 450(?) die. They seem to have been better in the past though as I have an older 480 watt antec somewhere that works. I've got a 750 watt PC Power & Cooling now that is rock solid.

The 250 watt might work. It won't support a decent video card but those are mainly for gaming and it doesn't sound like you are building a gaming rig.

AMD is good for a budget build. They seem to change their sockets around more than Intel though. My motherboard is nearly three years old but my CPU is much newer (Intel Q9550). What I'm trying to say is if you want to get a cheap CPU and a better one down the road when prices fall get a newish socket (socket 775 for Intel, I don't keep up with AMD but I think its socket AM2+). There are newer sockets but that is out of your budget I'd bet.

You could probably get a free computer off of craigslist to play with. The parts will likely be of no use in the new build but you could take it apart and put it back together for practice without fear of releasing the factory installed smoke.

Interesting, KPT.  I wonder why the run of bad luck?  For the most part I have used nothing but various flavors of Antec in my and my client's machines.  I've lost track of how many it's been.  Never a hiccup with any of them, though.
I do calculate the power requirements based on the hardware, and install a supply with enough overhead so it doesn't have to work hard under heavy use.   That might have something to do with it.
I've used Rosewill and CoolerMaster in that past, too, but only one of each.  Not enough to build any kind of representative sample.

My sister's Antec died, too, actually, but it didn't take the rest of the computer with it.  One of the two fans it had in it died, so it needed to be replaced.  We replaced it with a slightly beefier version from the same brand.  I think the one she had was one of their budget models that they ship with their cases, which don't tend to be as good as the ones that are sold separately.

In my experience - I've assembled literally dozens of computers in the Army and at work - the main work with assembling a computer is determining what parts you want in it and actually procuring them (some stuff, like advanced cooling system, can be pretty difficult to get) rather than actually the physical actions involved in assembling it.

My old 'puter desperately needed an upgrade, so I started looking, and for the cost to replace my fried LAN card, memory upgrade, and newer hard drive, I figured I might as well spend a few more dollars and get a whole system that is much faster. I just recently put this one together:

motherboard (http://www.newegg.com/Product/Product.aspx?Item=N82E16813131370)
cpu (http://www.newegg.com/Product/Product.aspx?Item=N82E16819103210)
memory (http://www.newegg.com/Product/Product.aspx?Item=N82E16820104008)
hard drive (http://www.newegg.com/Product/Product.aspx?Item=N82E16822148397)
power supply (http://www.newegg.com/Product/Product.aspx?Item=N82E16817339019)

My objective was to keep it as cheap as possible. I used my old case, cd/dvd drive, monitor, mouse and keyboard. Zero problems running Ubuntu. Just make sure you keep touching the grounded case while you assemble it so static doesn't kill your new computer before you even turn it on.

I just reread your post, don't bother collecting parts for a year or two before putting it together. They may or may not work with anything that's available in a couple years, and if they are still available next year, they will be 1/4 the price and faster parts will be available for the same price you paid. Whether you do it now or later spend $300 all at once and order all the parts at the same time.

Thanks everybody. 

Mr. Bedlamite, thanks for the example parts list.  It is informative.  Looks like it was 200+, then?

The power supply link points to the hard drive, though.  Hope your new computer is super-duper.

If you have the intellectual horsepower to install Windows, you can roll your own PC.  Buy on the forward edge of technology, not the leading edge.  Dual core not quad core.  Mid range speed, not high speed.  Affirmative on DDR2 only buy lots of it.  From you apps list it sounds like 1 gig would work so get 2 gigs.  Every item you purchase will have a power requirements list.  Add it all up then buy a 500 watter.  I would not recommend re-using hardware from a store bought system.  Standards include physical dimensions BUT NOT ALL PHYSICAL DIMENSIONS.  Store bought systems engineer physical dimensions for their convenience which may preclude you from substituting free range parts.  Save on aggravation and just start from scratch with a new box.

My sister's Antec died, too, actually, but it didn't take the rest of the computer with it.  One of the two fans it had in it died, so it needed to be replaced. 

Did the fan actually die, or was it just not turning on?  In many of the dual fan Antec power supplies, the second fan is thermostatically controlled.  It doesn't turn on unless the temperature in the power supply rises enough to require the extra cooling.  The second fan is usually the one on the rear of the supply.  Thus, the fan control doubles as a fan noise reduction feature.
That feature fooled me a couple of times until I realized what was going on.  I pulled a two of their power supplies from service before I realized what was happening.   Those two supplies have since been put back to work, and have been flawless.
I think a lot of "failed" Antec power supplies have fallen into this category.

eta: Sometimes it pays to read the fine print in the manual.  Something that I have to remind myself of frequently.

Interesting, KPT.  I wonder why the run of bad luck? 

Don't know, I think I remember reading Antec having quality issues for a period of time. The 550 watt was loaded down but not overloaded.
Core 2 Duo, 5 HD's at one point, 2 optical and a 7950 GT. It worked for almost a year and then would start randomly rebooting while gaming. I put an 8800 GTS in the computer and it would reboot before a game finished loading.

That was a smartpower. I RMA'd it and got an earthpower which is still working in a computer I built for a friend.

No, it died.  The bearings failed, and its death was rather loud. 

Fans do that sometimes, though, which is why I went ahead and replaced it with another Antec instead of shopping for another brand (that, and Antec was the only thing the local store had on hand).

Ah, so you fell victim to the "Screaming Bearings of Death."  As you say, that does happen.  I wonder if Antec uses ball bearing or sleeve bearing fans?

(And I wonder if I can copyright that "Screaming Bearings of Death" phrase?)

I've not built my own yet for lack of funds, but I have been studying the process and plan to do so.  All in all it does not seem that hard, the harder part is figuring what you want to do with it and going from there.

As to buying parts here and there I would avoid it and just set yourself up with a computer build fund, which is what I have done.  This way when I go to do it I know all the parts are compatible and that I'm getting something that is up to date.  Why spend fifty bucks today for a build happening a year from now, when you can likely spend the same fifty bucks a year from now on a part that is that much better? 

Computers are still one of those things where as soon as you buy something, something newer and better is available before you get the thing home, and available for the same price you just paid.  The best system I ever had (specs wise anyway....will never own another Dell) I bought new from Dell for over 2k.  2 1/2 years later I bought the computer I use now.  Computers with comparable or better specs as the Dell were going for just under a grand.  So save the money and buy parts all at once when ready to build.  Save buying a piece here and there for a car rebuild.

Manufacturer cases can sometimes be made to work, but it's a bit of a gamble, since they'll sometimes make some parts fit a proprietary dimension while making others standard dimensions.

My sister had an old gateway that I got from her after I replaced it with a custom one.  I used its case to put together a Frankenstein machine that's currently serving as a multimedia PC.  The only major modifications I had to make to the case was to take a hacksaw to the holes for the external motherboard connections so that I could install my own motherboard, as Gateway had made the holes specific for their motherboard.  Most aftermarket cases just have a large rectangular hole that allows you to fit a faceplate that the motherboard manufacturers include with their products.

A two year pc project is a bit long the way technology and prices go.
I would buy the motherboard and processor last in that case.
I've dealt with geeks.com for over ten years. Check the tech pages for info on building a system.
If you look at the dvd drive section you will see DL sata drives for around $20.00 no need to worry about using your old cd drive. In two years you may not find a board with IDE.
If I was to plan the build you are talking about I would get an AM2+ board with four DDR2 slots. You could put a single or duel core in it with 2 gig memory to start but upgrade later to a quad core with 8+ gig memory.
Memory prices don't seem to jump like they used too, but you never know. It's cheap right now.
Check your motherboard and video before buying a power supply.

Thanks again, all. 

Manufacturer cases can sometimes be made to work, but it's a bit of a gamble, since they'll sometimes make some parts fit a proprietary dimension while making others standard dimensions.

I'm thinking I'll order everything, and then see if it fits the old Dell case.  If not, I can always order a new case.  In that case.  As the case may be.

You could probably get a free computer off of craigslist to play with. The parts will likely be of no use in the new build but you could take it apart and put it back together for practice without fear of releasing the factory installed smoke.
.

I just discovered that one of the machines has a couple of capacitors bulging.  It's in a bad way; had overheating problems, and that was BEFORE I took off the CPU heatsink and then put it back together without any grease.   =D 

A guy I know has a Gig of DDR 1 and a Pent. 4 chip I was gonna put in there.  If his price is cheap enough, I'll go ahead and get the stuff, and install it just for "practice."  And I'll even use grease this time.   :angel:  Shucks.  I could even take out the mobo and bring it to Dad's auto shop, and have him solder in some new capacitors.  Have mysef a real bubba-fied compooter then.

That doesn't happen until you have everything stuck in a cardboard box from the grocery store, with a small oscillating fan that didn't oscillate anymore for cooling. Yes, it ran reliably. No it wasn't mine.

I wouldn't bother with 'salting away' used parts, excepting the keyboard/mouse/monitor.  You should be able to get by with a used DVD drive.  Maybe, and that's a big maybe, the case/power supply.

I generally consider the motherboard/cpu/memory to be a 'set' that I keep together - by the time I replace one, ALL are seriously out of date, it ends up being cheaper to buy all new as a set.  I'll generally keep a couple slots open for additional RAM.

For processors, should I look for an AMD or an Intel, or what?  If I use, say, a P4 HT, at 3 GigHz, will I be sorry I didn't hold out for a Dual-Core?

Given your timeline, I can't make a recommendation, they switch as to what's best every other month or so.  Both would work.  I WOULD hold out for at least a dual-core, makes the system respond SO much nicer when one of the programs is trying to consume 100% CPU power, as it generally leaves the other core alone.

Quote
Will a 250 Watt power supply work alright, or does it have to be a 450 Watt, or something?  I'm thinking about using the case/power supply from a Dell GX240.  They have a 250 Watt supply. 


My concern here is that Dells might have a propriatary power supply, in a propriatory case, designed to use a propriatory motherboard.  For a basic computer, 250 watts would be enough, but a good quality 300-400 watter(such as a seasonic) might be better.  I'd look for 80+ certification.  It's hard to find quality low wattage power supplies, but they're most efficient around 60-80% capacity.  So if your computer operates between 240-320 watts, the 400 watt would be the best choice.  180-240 for the 300 watt model.

There's a big article over at anandtech on this.

Quote
If I use an older CD drive, will it be problematical, or is one as good as the other? 


Noise, speed, reliability would be the only concern, and I hope it's a DVD drive, not a CD drive.  Oh, and an older one will likely be PATA, not SATA, the newer standard.  PATA heads are starting to get a bit rare on motherboards, and a new DVD burner is like $20.

I just built our current PC three or so weeks ago. As had been said, most of the work is choosing the parts. If you're doing this as a hobby or such, go for it. However, if you're looking at the real low end of the scale because of cost, IMHO it is often not a horrible idea to go with something like Dell.

That said, you've already listed the roles you want this PC to fill, so if you throw these geeks a dollar range to work with, they'll probably throw half a dozen configurations for you to peruse at newegg.com or such.  =D

I can build a high end computer and save a good grand over the cost of a similarly configured one from any major manufacturer.  Such a computer would run between $1-1.5k, but would run $2-3k from dell, alienware, etc...

On the low end, I can't beat dell, hp, and the like.

Agreed. My build would have cost about $900 more coming from Dell, yet still has better quality components.

Everyone has given great advice.  Most are telling you about Newegg.com, great company for others.  I had a order problem that they didn't resolve(shipped an order as complete, missing 4 parts, no parts showed, fought a refund).  So, I'll throw this in the mix an an example. 

I recommend Tigerdirect.com.  They are my only supplier and I have never had a problem with parts/warranties/shipping or anything else.  I run my own business doing custom builds, upgrades and consultaion.  I build, on average, 3 systems a month.  I just ordered this for a customer, at a higher cost...

I'm looking to replace the processor in my old custom-build computer, probably with a used P4 from ebay.  Can I use any processor that fits the socket, or are there other compatibility issues? 

Or since it has a couple of bulgy capacitors should I regard it as UXO?

Ask Balog about TigerDirect sometime.

They've been known to cut corners a bit too much.

I run a business doing builds, upgrades, and consultation, too.

I only buy and sell professional-grade corporate lease turn-in machines now.

When you are the warranty, you don't need the deck stacked against you.

I've done some buying from TigerDirect, and while I've never really had a problem with them, their prices and selection leave a bit to be desired, though they do sometimes have things Newegg doesn't.

Never had a problem with Newegg in the several years I've been buying them.  I've only had to do two RMA's due to defective products (which is something that happens every once in a while), and while it was a bit annoying it wasn't that bad.

I'm looking to replace the processor in my old custom-build computer, probably with a used P4 from ebay.  Can I use any processor that fits the socket, or are there other compatibility issues?

I'm pretty sure you can, though if your motherboard doesn't support certain features of the later P4s such as hyperthreading and your CPU has these features you won't get optimal performance.

Or since it has a couple of bulgy capacitors should I regard it as UXO?

I'd ditch the motherboard if it has severe problems, actually, or even small ones.  Small problems seem to have a tendency to morph into big problems down the road. Though, if this isn't intended as a main computer, it probably doesn't matter all that much, so long as you're aware that you may have to replace the motherboard and quite possibly anything connected to it if it decides to become an ex-motherboard.

fistful, you need to make sure your motherboard will support the processor.  Your machine uses a socket 478 Pentium IV CPU.  However, not all P4s are created equal.  Make sure your motherboard can support the front side bus (FSB) speed of the processor.  IIRC, Intel made P4s with FSBs of 400, 533, and 800 mHz.  If you put a fast FSB CPU in a motherboard that cannot support it, it may run, but it could be slower than the original CPU.
You should be able to look up the specs of the machine on Dell's support site.  They're pretty good at listing that stuff for the machines they build.
Enter the service tag of the computer on the Dell site to get the exact info for that machine.
PM me if you have questions.

Nothing good comes from a bulgey capacitor.  Don't put yourself in a position where you do it cheap again and again and again . . .

The computer I'm talking about is a custom-build someone made for me, not the Dell. 

It's not a main computer at all.  I've had some serious problems with it, so I'm not expecting to lose much if I screw it up.  I'm guessing the capacitor problems are related to the over-heating problem it had. 

Is replacing the capacitors as simple as soldering in new?  I could get someone to do that for me, but I'm pretty sure he's never dealt with a motherboard before. 

What's a good source for capacitors? 
Title: Re: So you want to build a computer...
Post by: RocketMan on May 02, 2009, 02:33:21 PM
Fistful, the same FSB requirements hold for any socket 478 motherboard.  You will need to find out what FSB speed(s) your custom system board can run before you attempt to upgrade the CPU.
Regarding changing capacitors, it can be done, but it should be by someone with the right experience and tools.  It's not for the faint of heart.
I've purchased good quality high-temperature, low resistance capacitors from Mouser Electronics to repair motherboards.  You definitely have to know what you are buying.
You could potentially get an exact replacement of that motherboard if you look around.  Motherboards of that vintage are pretty cheap as a rule.  What is the make/model number of the board?

If replacing the capacitors costs too much, I won't even mess with it.  It has taught me to really dislike small form factors, although it's over-heating problems are my fault.  But I would think larger cases would have less trouble with heat build-up.  Not much room to work in there, anyway.

The "guy I know" who might wield the solder gun for me is my Dad, professional auto mechanic.  I doubt he's ever worked on a motherboard, but it certainly would not be his first time working with solder.  I don't know if that's enough "experience and tools" to do the job.  Then again, this motherboard might be good practice for one of us. 


Motherboard info:

Gigabyte P4 Titan
GA-8SLML
SiS 650GL chipset

2002 vintage

I have the manual, utility CD, box, etc, for the motherboard.  The (poorly-translated) manual says:

Socket 478 for Intel Micro FC-PGA2 Pentium 4 processor
Supports Intel Pentium 4 (Northwood, 0.13 ~m) processor
Intel Pentium 4 FSB 400MHz

I have tried to look it up on Gigabyte's website, but they don't even list it, even under "legacy."  Too old, maybe? 

Edit:  It's currently using a Celeron, 1.7 GHz.

Or just replace the motherboard with something newer, with DDR2, USB 2, etc?

Your Google-fu is weak (http://www.gigabyte.com.tw/Products/Motherboard/Products_Spec.aspx?ProductID=1401)

I'd start over with a new motherboard. That one has pc2100 memory and no SATA.
Title: Re: So you want to build a computer...
Post by: Perd Hapley on May 02, 2009, 04:12:33 PM
Hm.  Okay.  Thanks. 

If I junk this motherboard, can I transfer the XP COA to another system?

Fisty, get an Intel D865GVHZ.  Sweet boards.  Socket 478 P4 CPU support with 400/533/800 FSB, so it supports the fastest P4 processors.  It has eight USB 2.0 ports, on-board video, audio and LAN.  It does take DDR memory with dual channel support, PC3200/DDR 400, not DDR2, but that's not a big thing.
It also has both parallel IDE and SATA drive connectors.
I've got two of them in service in shop computers and would like to have a couple more.  They run ~$40-$50 depending on where you find them.

The capacitors to fix the old board run less than $1 each.  But it does take some specialized tools and expertise to desolder and remove the old parts from a circuit board.  If your Dad has never done that before, expect your old board to just be a sacrifice to the experience gods.

If the Windows COA is on the case you would put the new motherboard in, then you are good to go on reinstalling Windows.  There are ways to avoid reinstalling Windows on new hardware, but it is tricky and labor intensive, even for a geek like me who has done it before.

The wife just got back from Goodwill.  She found me a Linuxgruven.com t-shirt.  It was apparently a scam company founded in this area back in 2000 that pretended to do IT work, but just made its money by requiring new hires to pay $3000+ for training.  Folded the next year, after the founder got nabbed for some insurance fraud thing. 

But hey, it's got a penguin on the back.   =)

COA is just a number - cut that part of the case off, and tape it to the new case, so you don't lose it.
 
I recently had a bad experience with Tiger Direct... I probably should have kept escalating until I got someone to speak English...

Somewhere, I got the idea it was tied to the system's hardware.  If not, sweet. 

So, what keeps me from using the same COA for all my machines?

Against your better judgment, folks, I'm going to keep playing around with the homebrew and its janky motherboard.  I just bought a ten-dollar CPU from Ebay, to upgrade from a 1.7G Celeron to a 2.2G Pentium 4.  I'm also upgrading the memory (DDR) from 256 to 1G.  Guy at work is selling it to me. 

I'm gonna swap some other parts, so just in case the motherboard fries everything, it's wearing the least useful of the hard drives, CD-ROM drives, etc, that I have on hand.

fistful:

If you ever get down Dallas-way on the first (or third) Saturday of the month, you could do well.

I haven't been in a couple years, but they have "First Saturday" and "Third Saturday" computer & pc part bazaars held under the elevated freeway in the West End of Dallas.

Used to be able to buy any and all sorts of PC stuff and many local vendors would show up and set up temporary shop.

Think, "gun show for computer geeks."  New, used, auctioned-off-by-the-pallet, whatever.  I remember when a one of hte telecoms went tango uniform, this guy was selling Sun workstations out of his box truck straight off the pallet. 

If those don't trip your Zombi-Franken-PC tinkering self, we have three Fry's and one Microcenter.  They rock so hard, I only buy 1/4 of my PC componentry online, these days.  They make BestBuyCompUSACircuitCity look like pathetic also-rans.

Come to Dallas.  It is Sin City for geeks.

Not a bad way to go, fistful.  If it dies, you aren't out much.  And you might learn a few things about computers in the meantime.

Updating a BIOS is only scary if something goes wrong.  :O  =D

Seriously, make sure your floppy drive is clean and functional, and you use a good quality floppy disk if you go that route.  Not so much of a concern if you can do the update from a thumb drive.

Not mandatory, but it wouldn't hurt to put the system on a UPS if you have one, just in case the power decides to blip in the middle of the update.

Well, the build-a-computer project may be pushed back even farther.  I just purchased a Dell GX620 for about one bill.  It has the good stuff I had been hankering for - a Gig of DDR2, 2.0 USB, with 6 in back and 2 in front.  2 USABLE ports in front, as opposed to these old Gateways and this old Dell with the funky grey door in front. 

It should be a good fit, because I already have the XP Pro install disk and drivers/utilities disk for this particular model.

Now, I'm just going to buy a student-license copy of MS Office, and some moar RAMs for these old machines, and maybe a spare monitor, and this outbreak of computer stuff-getting will probably subside for a while.
