COOLER MASTER COSMOS SE

Cosmos SE is the successor to Cooler Master's flagship Cosmos II ultra-tower computer case. It delivers the classic racecar look and feel of its predecessor in a smaller, mid tower package. Rails forged of aluminum provide sturdy handles for transporting your system. Although smaller compared to Cosmos II, SE still exhibits high-end features such as expansive support for all-in-one water cooling systems and hard drive storage. With the ability to install up to eight cooling fans or three radiators at once, Cosmos SE is capable of housing extremely powerful cooling components.

Iconic, Racecar-Inspired Design

Superior Water Cooling Support

Cosmos SE continues a lineage of classic design inspired by the supercars of today. Curved aluminum handles, sleek lines, and stylish blue LED accents provide a truly premium aesthetic.

Cosmos SE is capable of supporting up to three radiators at once, including a 120mm in the rear, 240/280mm on top, and a 360mm at the front. Cosmos SE allows you to pack massive cooling power in a perfectly sized enclosure.

Plentiful Storage Space for HDDs/SSDs

Large Cable Management Space

Uniquely designed combo trays can hold two SSDs each, providing support for up to 16 SSDs or eight HDDs in the hard drive cages. Two additional SSD mounting points are located on the backside of the main drive cage, allowing for a total of 18 SSDs.

A nice, clean setup is important for any high-end build. With Cosmos SE, you've got ample space to neatly store any loose cables with approximately 1.3-inch (34mm) of cable management space.
