Goodwill around here takes old computers. Not to resell, but to recover precious metals - individually there is not enough scrap precious metal to make it worth kicking off a cliff but in bulk there is enough money to make it worthwhile for Goodwill, the smelter, and whoever else is in the chain.
Besides, Goodwill disposes of the parts that are not sent for recovery. There is some money in that as well.
Get a receipt. Use it to offset the Obamacare ACA tax.
stay safe.
