Someone in Japan has made a G5-like Cube enclosure and put the parts of a G4 Cube inside: http://www.conf.co.jp/new_folder/making/cube_9.html
Very professional job, I think. The complete DIY guide starts here (in Japanese, though): http://www.conf.co.jp/new_folder/making/cube_1.html
edit: he enclosed a 4-port USB hub as well to have 4 USB ports on the front.
