Hey guys, I purchased 5 PowerMac G5's AS-IS yesterday for $40 a piece. I've got a few things to work through: 1- doesn't boot what so ever (taken apart for parts and using case for a PC) 2- 1 boots perfectly. Not a single issue. 3- turns on, fans spin up, but I get 1 flash white light every 5 seconds. Nothing comes on screen. Tried with working ram, hard drive and video card. About a minute later the fans spin up to full blast. The hard drive works fine in it.. 4- the same as #3. 5- untested, will get a response soon. For #3&4 could it be needing the original hard drive? One of them had an extra 500gb hard drive in it... Let me know what I can do... Thanks!
