Here's a clever blending of Apple past and present, in keeping with our post yesterday on Mac mini mods. Rich Willis has managed to stuff a Mac mini, an external HD, and an Airport Extreme into the clear plastic shell of an old G4 Cube.
Moving very slowly (to avoid melting the acrylic Cube case) he cut away the back of the case to give access to the various ports and then installed some acrylic supports to hold everything up. Voilà -- the Cube lives again, sorta. Rich has a gallery up that documents the entire process.
