Twelve South “BackPack” for iMac and Apple Cinema Display
It never hurts to have a little extra storage space in your workspace to keep things tidy and organized.
Twelve South's BackPack is a small, adjustable shelf you mount onto the front or back of your iMac or Apple Cinema Display. It holds up to 3.5 pounds, so it's great for external hard drives or USB hubs, or perhaps your iPhone, wallet, and keys, or whatever other small items you might need to stash out of your way while you work.
Installation is simple:
The shelf comes with four vertical, soft silicone pegs that can be arranged in various formations to hold taller vertical drives and such — or even a MacBook Air — in place.
