I kinda want one to screw around will older versions of OS. I don't really care about OS 9, as any apps that it has I can just run in Classic. But here's the thing: I'm pretty young, so I can't afford a PPC mac just to mess with. It probably wouldn't work as a media box because it can't do flash, is there a way I could wirelessly backup files from my Mac mini to it? I had an iMac G4 in mind.
