Update: Seems like the Optiplex is sold

OK, more stuff.

I was able to get a stripped Dell Optiplex up and running with stuff I found while cleaning the apartment. It's one of those thin Optiplex units with only one 5 1/4" drive bay. The machine has a Pentium II 450, 192MB SDRAM, 20GB hard drive, DVD-ROM, Netgear 10/100 PCI NIC, and 56k PCI modem. Video (ATI Rage) and sound are on-board. $100 takes it (shipped free in the continental US).

Notes: There is one free PCI slot remaining. I think the slot is also shared with an ISA slot. Dell service tag: 66NRI
