Here are some of the first pictures of the Master Case 4 and Master Case 6 by Cooler Master. Both cases are built on a slightly different design language than the Master Case 3, Master Case 5, and Master Case Maker 7, in that they lack the signature top-edge hexagonal element housing the front-panel. If you ignore that bit, the two cases to feature the same elegant cuts and creases from the rest of the lineup. The Master Case 4 is a micro-ATX tower, with room for full-fledged, liquid-cooled micro-ATX gaming PC setup, including room for a pair of 240 x 120 mm radiators. The Master Case 6, on the other hand, is a mid-tower with more of the same features. We don't believe the Master Case 4 and Master Case 6 will be in the same price-band as the rest of the Master Case series, but we'll have to wait and watch.
