We’ve always wanted to fill that hole on the iMac’s leg with something other than just cables, but to the best of our knowledge, no company has come up with something meaningful to do with it. Now, with the announcement of mBack ($169-$349) from mLogic, the hole has a purpose beyond cable management. mBack is an external hard drive that takes up no space on your desk; it mounts right on the iMac’s back, leaving you room for all your other gadgets.

mBack is going to be available in 1TB, 2TB, and 3TB models, each with a USB 2.0 connection. The mount is designed to fit on any of the aluminum iMacs, dating back to the 21” and 24” models from mid-2007, as well as the LED Cinema Display and the Thunderbolt Display. mBack’s drive isn’t USB powered, but the company notes that it uses up to 30% less power than other drives, and runs cool and quiet. We’ll see if it lives up to expectations when it’s released in November.
