I have a 400mhz Gateway PC for sale. Windows 2000, Office, MusicMatch, Nero, etc. installed. It has a 16x10x40 cd burner and a 3.5" drive. It has an ethernet card but no modem. It can run classic emulators fine, and is a good word processor/email computer. I used it all through college and it's a solid machine. I also have a nice 17" VGA monitor.

PC- $50
Monitor- $50

Together- $90.
