Buying two of these ASAP.

BackPack is a sturdy, sleek looking shelf designed exclusively to attach to the back of iMac and Apple Cinema Displays. This handy little piece of heavy gauge steel is perfectly sized to hold hard drives, USB peripherals or even a Mac mini. (If you use it to display your favorite Star Wars action figures, we’ll totally understand.) You can use the perforated base to tie up that web of cables lurking behind your Mac.
