Today 3DXtreme is pleased to present our latest hardware review of a recently released mid-tower Case from Cooler Master. Cooler Master has long been known for delivering some of the highest quality Cases to the market. The ATC series was a personal favorite of mine and I owned three of them over the years. When heat and the need for more space shifted my focus to full-tower Cases I was sad to have to leave my ATC Cases behind. Today?s Case, the Mystique 631, is an aluminum mid-tower available in a silver or black brushed aluminum finish.
