Warning use either a SATA Power or Legacy Power connector. Do not use both which may result in damage to the hard drive. (It used the serial data connector and the legacy power connector.)
I don't have any spare drives like that, mine are all IDE. :( The good news is you can buy SATA refurbs really cheap, and you can use either a 3.5" or a 2.5" drive (with a $2 Molex-to-SATA adapter cable.)
You
may have trouble installing XP unless your install CD has the SATA driver merged in, and you can only load additional drivers during install using the diskette drive. There's a BIOS setting to switch the SATA controller to IDE legacy mode, but if you turn that on you have to leave it on (I don't know what you give up by doing that) If your system has a working diskette drive, all this is not a big problem.
If you need a Win XP Pro install CD with SATA drivers, let me know and I can burn you one. It probably won't have all the other drivers you need for your motherboard, but you should be able to download the other drivers from Acer and install them later. If you need XP Home, I don't have media for that and your license key wont work with XP Pro.
Or you can just put Linux on without all the fuss and drama of a scratch install of Windows (but then you'll have Linux instead of Windows)
