what do you do with your old pc's? the 200 Mhz pentiums, 233 mx, pII's, cyrix, amd's, etc. I am using a few to play and test stuff. They are not that old and can still perform quite well, but have some just collecting dust taking up space. pretty sure nobody will want them so i can't donate them. plus i don't have any OS' to give away with them either. i can bring them to work and throw it in our hardware dumpster... but i seem to be a pc/pc parts junk hound. what do you do.
