Call us crazy (our parents sure have), but we think this thing is awesome in a "this can't be a real item for sale" kind of way. TwelveSouth's "Mac exclusive" BackPack shelf attaches to the back of iMac
and Apple Cinema Displays
, providing a place for your Mac mini
, hard drive -- or your Dr. Beverly Crusher figurine. They run $29.99, or you can get a six-pack for $150. Yes, a six-pack.
