I have several x86 machines sitting around at home that I can beef up some before getting rid of. a few Slot1 pentium 2 machines, an AMD k6-2 machine or two, probably one or two pentium 3 machines... If anyone is at all interested, i'll start going through them tonight and listing off the specs. i also have a crapload of random hardware lying about. i can list that off too.
scsi pci controllers, isa modems/sound card, serial cards, video cards etc etc. lots of ram types.
