Well, I'm just tossing the idea around in my head (maybe this belongs in mods more?), but I can't find any info on somebody doing an ATX conversion of a G5 iMac. I seem to recall finding some stuff about using an ATX PSU, but not a case conversion. I also seem to have trouble finding the dimensions of the actual board. The reason I'm wanting to do this is I don't really own any PPC macs any more, but I'd still like to. At the same time I really wanna get a G5 system as opposed to a G4 and I figured if I could find a G5 iMac with a busted screen for cheap this would be a great way to go about it. Not to mention it would have a way better PSU that the iMacs typically seemed to have (I'd also replace the logicboard caps).
