I know I can get the bulk of it here: http://www.dvwarehouse.com/Board,-Power-Button,-PowerMac-G4-Cube-p-25616.html But is there a controller board? I can't find any documentation on this thing. I want to use it for a PC. Making an acrylic top is no problem. Just looking for pin-outs, dimensions, and maybe some pictures of someone else dissecting one.
