I've got an 800 MHz iMac G4 that I'm considering selling.
It has passed extended Apple hardware tests, and has successfully installed OS 9. The 15" LCD works perfectly.
The only reason I'm interested in selling it and abandoning a planned headless hack is I can't get a better resolution than 1024 x 768 x 60Hz on an external monitor (a hardware limitation of this iMac model). My deskspace is too tight for a second monitor - even an LCD.
What you don't get:
Hard drive
CD drive
power cord
memory
kbd. & mouse
