Cooler Master has revived its gargantuan Cosmos case product line; as demonstrated by the brand dedicating a whole table to two behemoth samples. Massive chassis designs are not particularly "de rigueur" nowadays, but 2025 revivals could be appropriate fits for ever-growing graphics card profiles, and extra elaborate cooling setups. Two different configurations were presented; as denoted by product placards and differentiated by modular panel selections. This year's refresh supports modern hidden and back-connector products.

The Cosmos 2025 "Water Cooling" demo unit's foundation consists of a non-specific Intel Ultra 5 processor, a customized (watercooled) GeForce RTX 5090 card, and an ASRock Z890 LiveMixer WIFI mainboard. Cooler Master has installed their fancy X Pro waterblock system; the visiting TechPowerUp team noticed that these components occupied only a small portion of internal volume. The 180 mm long MWE Gold 1250 V2 PSU looks relatively dinky, in its elevated perch. A radiator setup seems to feature absolutely huge airflow fans (maybe four in total); two of these units are visible in some of our photos.As befits its name tag, the "Air Cooling" Cosmos configuration is built around a V8 3DHP (3D Heatpipe). This tower cooler tempers AMD's reigning gaming CPU champ: Ryzen 7 9800X3D. Cooler Master's Taipei crew presented a very tidy and heavily compartmentalized custom build; this almost Apple Mac Pro-esque setup covers up the vast majority of components.The CPU thermal baffle's cutout grants a peek at the V8 cooler's top face. A Cooler Master-branded GeForce RTX 5090 graphics card is completely obscured by the Cosmos 2025 GPU baffle.
