So I have a 17" iMac G5 it is the 1.8 ghz model. Everthing inside is original and I just put some more RAM in. I also cleared the hard drive so it is blank except for the os x. It is runing 10.5.8 I belive, whatever the newest possible one is for the computer. 80gb hard drive and it comes with original keyboard, mouse, manuals, and box. It is in almost perfect condition. No scratches or anything. About how much is it worth?
