Check out this incredible mod of a PowerMac G4 Cube turned into a miniature version of a PowerMac G5 with the its distinctive aluminum enclosure. It appears, if you look at the details of how he did it (the hyperlink at the bottom), that he made the entire enclosure out of ABS plastic sheet stock. Incredible. Just to be clear, the processor inside is a G4. The only G5 thing about it is the case design. Cute little bugger, don’t ya think?
