That's a great find on the G4, for sure! I have always wanted one, but I'm really not sure where I would put it and what I would do with it. I would love to put one in the kitchen, the small 15-incher, but I am almost certain that if my wife left and returned to see an iMac on her kitchen counter that it wouldn't stay there for long ha ha! I wish they had stuck with that design when they added the G5 processors to the iMac, it would have made such an iconic design stay a lot more relevant for a lot longer. Still, I bet the fan noise would be pretty horrific in such a small enclosure for the CPU etc.
I think what I’m going to wind up doing is connecting it to my media server. My fiancée and I keep cooking videos saved on a partition of my server. It would be kind of cool to use it as a video player in the kitchen. That, or I’ll use it as a dedicated jukebox. Haven’t decided yet.
