How do you store all your testing devices?

Hi there, we're in the process of getting multiple testing devices (phones/tablets) for iOS and Android development. I don't want to stack them on the corner of a table and was wondering if any of you have a good idea to store them in a clean way? I was thinking of using a wall shelf (something like http://www.ikea.com/ca/en/catalog/products/S99903646/) and use some kind of stands to keep them well organized.

Any ideas are welcome :)
