I recently found in a dumpster a 17' inch iMac G4 (1Ghz, 80 HD, superdriver, 512MB). All components seem to be ok. When I power up the PC, you can hear the chime, but no image comes up. You can see there is backlight but the screen is as dark as night. I really do not care about the lamp case. I was hoping to move all the components to a spare PC case that I have in my basement. Can I use a regular ATX power supply? If I can use a regular PC case with a external LCD monitor (attach to the MB's external LCD port), that would be awesome. Any hints?
