PC Apex posted a review on the Cooler Master Mystique 632 ATX Case

The first things you'll notice when removing all the packaging are the unique front doors and its light weight due to its aluminum construction. The doors are set up in a clam shell design which open simultaneously thanks to a gear mechanism linking them together. The action of the doors is very smooth and there are three magnets in the right door to keep them securely closed.
