Cougar late last week rolled out the MX331 line of ATX mid-tower cases. The case comes in four variants based on looks and functionality: the base variant has a mesh front and an opaque left side-panel with some fan vents. The next variant comes with a mesh front, and tempered glass side panel. The variant after that, the MX331 Mesh X, builds on this with RGB embellishments and an included 120 mm RGB rear exhaust fan. The top variant has piano-black acrylic front, with tempered glass side panels. All four variants are internally identical, the top two come with additional USB 3.x ports.

Internally, the MX331 comes with a conventional horizontally partitioned layout. The top (motherboard tray) compartment can hold graphics cards up to 35 cm in length, and CPU coolers up to 15.5 cm in height. Storage options include two 3.5-inch trays that can each hold 2.5-inch drives; and two additional 2.5-inch mounts behind the motherboard tray. Ventilation includes two 120 mm front intakes, two 120 mm exhausts at the top, and a 120 mm rear exhaust. The case measures 481 mm x 204 mm x 443 mm (HxWxD). The company didn't reveal pricing.
