I have a PowerMac 7200/120 MainBoard and a Working Power Supply. The case is trashed. Missing Sleds, dented up all to hell. Plus I want to use a different CD drive than the apple provided one since I have a SCSI CD Recorder that would work but doesnt fit the space it goes in, its too long. So I have this Idea to do an ATX Conversion. Any Ideas? I want to mount the board in an ATX Case, but I'd like to try to use an ATX PSU if possible. This is all practice for doing a beige G3 conversion. Im ordering a Beige G3 mobo from eBay and building a computer out of it.
