Taking advantage of OS X's Clamshell Mode means you can use your notebook — closed — with an external display, keyboard and mouse easily. It's a great way to get more pixels in front of you, but can leave your desk cluttered.

In the same vein as the TwelveSouth BookArc, the Rain Design mTower is designed to keep your MacBook Air (or Pro) up, off your desk.

The mTower comes with four different adapters to secure various different sizes of MacBook, from the 11” Air to the 17” Pro. Carved from aluminum, it's good-looking and more importantly, sturdy. Check it out on Amazon.
