This is simply one of the BEST accessory inventions for the iMac! I found this in the Apple Store and placed my external Seagate HD (I use for Time Machine) on it in order to keep it off my desk. The HD is now out of sight, I don't see the wire hanging anymore and I don't have to keep moving the HD to clean around it. The Twelve South even has a little rubber pad for your item to sit on so it doesn't move around. Absolutely perfect!
