The Black Knight Mid-Tower Case features a swing away front bezel which shields the external drive bays when not in use and maintains the polished look of the case. The swing away door is counter balanced on a sliding rail system which allows you move the door from the front bezel area to the left hand side of the case. The Ahanix website has an animated file which demonstrates how this function works. This feature is quite unique and has only recently been included in a few case designs from rival companies. In order to keep the door closed two small magnets are embedded into the door frame.
