I have an empty 9500 case w/power supply. I'm wondering if anyone knows whether I can stick something other than a tsunami 9500 motherboard in it? A 6500+ performa series? 9600's? A G3? Are the power supplies standard and compatible with Mboards older than a 9500? Has anyone out there managed to "build" their own mac systems from "scratch"? Hate to see this unused case go to waste, I was thinking of using it to store all my extra hdrives and connect it to my pmac, but would find more enjoyment in building up a system from scratch. any help and suggestions would be greatly appreciated.
