I still have about 7 of these Compaq Deskpro 2000, P120, 16M RAM, Quantum Fireball 1.6G HD, Floppy, Parallel, Serial, VGA on board, low profile with 5 slots on riser. $30/ea. I say about because I'm not bothering to check them out unless someone's interested, but I think they all boot ok. They make great Linux firewall/routers.
