If you internet gods exist...

on this message board, I need you now. I want to know what is the best resource that gives information regarding the rehabilitation of old computer parts. I was given 7 old computers (4 p4 based motherboards + tower, some with HD, CD/DVD, video cards etc.) and im looking to see how I can test them to see if they are any good. I want to build a few computers as give them away as gifts to loved ones.

anyway, please let me know if you check these forums

and does anyone play World of Warcraft? just curious.
