COOLER MASTER COSMOS Alpha EATX Full Tower Cabinet ( Black Silver )

The Cooler Master Cosmos Alpha is a full-tower PC cabinet engineered for enthusiast and high-performance builds that demand maximum space, airflow, and component flexibility. Finished in a striking Black and Silver colourway, the case pairs tempered glass panels with a metal chassis to deliver a premium aesthetic without sacrificing structural rigidity. At the heart of the Cosmos Alpha is Cooler Master's FreeForm 2.0 platform, which centres on a sliding motherboard tray. This mechanism lets builders reposition the board to reconfigure the interior between air-cooling and liquid-cooling orientations, and it also allows fine adjustment of the GPU-to-side-panel distance to optimise airflow or put graphics card aesthetics on full display. A sliding adjustable fan bracket complements this by letting fans be repositioned closer to specific heat sources without tools. Cooling support is extensive. The case ships with three pre-installed fans — two 200×38 mm front fans and one 120×25 mm Mobius rear fan — and can accommodate up to 15 fans in total across front, top, rear, bottom, and side-mount positions. Radiator clearances reach up to 420 mm on the side mount, 360 mm on the top, and 360 mm on the bottom, making the chassis compatible with virtually every AIO cooler on the market. Dust filters are fitted at the top and bottom to help keep internals clean. Compatibility spans Mini-ITX through to E-ATX and EEB motherboards across eight expansion slots. GPU clearance extends to 400 mm, CPU air coolers up to 186 mm tall are supported, and ATX power supplies up to 240 mm in length fit without modification. Storage is handled by two 3.5-inch HDD bays and two 2.5-inch SSD bays (tool-free configuration available when CPU cooler height is under 165 mm). Front I/O is modern and comprehensive: four USB 3.2 Gen 1 Type-A (5 Gbps) ports, two USB 3.2 Gen 2×2 Type-C (20 Gbps) ports, and a 3.5 mm headset jack. Cable management benefits from 53 mm of clearance behind the motherboard tray, and included accessories cover a VGA card holder, a decorative cover, and a right-side cable cover.
