Cougar today introduced the MX660 Mesh RGB-L, an ATX mid-tower case. A highlight of this case's design is its front-panel, which features a "3-D mesh." A coarse outer mesh extends along three sides of the front-panel, concealing a finer, flat inner mesh that filters dust for the front intake that supports either three 120 mm or two 140 mm fans; and radiators up to 360 mm x 120 mm or 280 mm x 140 mm in size. The top-panel has another such large fan vent, supporting the exact same combinations of fans and radiators. A 120 mm rear exhaust makes for the rest of the case's ventilation feature-set. Three 120 mm fans with ARGB lighting come pre-installed along the front panel, and the case includes a 6-channel ARGB controller that can toggle between presets at the push of a button on the front-panel, or sync with your motherboard's 3-pin ARGB header.

The Cougar MX660 Mesh RGB-L features a tempered glass left-side panel, behind which is a conventional horizontally partitioned layout, with the upper compartment serving up room for motherboards as large as E-ATX, graphics cards up to 41 cm in length, and CPU coolers up to 16.5 cm in height. The lower compartment has a 20 cm PSU bay, and two 3.5-inch drive trays that can each hold 2.5-inch drives. An additional three 2.5-inch drives can be mounted behind the motherboard tray. Front-panel connectivity includes two USB 3.x type-A, one USB 3.x type-C, and HDA jacks. The case measures 213 mm x 495 mm x 474 mm (WxDxH), dry-weighing 6.3 kg. The company didn't reveal pricing.
