TestFreaks posted a review on the Icy Dock 2.5" to 3.5" Hard Drive Converter

Icy Dock has sent me over quite a little ingenious product, it takes any 2.5" hard drive and essentially turns it into a 3.5" one. This can come in handy for many things including of course using it inside of your PC, or even inside of an external enclosure, the Icy Dock Convertor can make your 2.5" drive go anywhere a 3.5" can.
