COSMOS II - 25th Anniversary Edition

To celebrate Cooler Master’s quarter-century birthday, the brand introduces the COSMOS II 25th Anniversary Edition. A tribute to Cooler Master’s original and iconic COSMOS case. This special edition features an updated streamlined design with dual curved tempered glass side panels accentuated by two distinctive brushed aluminum handles. The smooth, brushed aluminum touch of the front and top panels refresh the case with an updated design, while the curved tempered glass side panels can unlock and swing open like on a luxurious race car. Moreover, the case has been updated with an aluminum motherboard tray and partition plate for an even more premium touch.

 Hidden behind the front slide cover lies a stack of hot-swappable drive bays. The black and silver interior provides enough space for oversized XL-ATX motherboards equipped with four graphics cards. A second slide cover on top hides the Advanced Control Panel to manage up to 8 fans and their respective LED lights. A perfect embodiment of Cooler Master’s innovative past and future, topped with elegant looks, rich expansion options and slick features, this COSMOS Ultra Tower is the next edition to our PC enthusiast “dream case”.

Unique dual curved dark tempered glass side panel design – Both sides come with beautifully crafted curved tempered side panels that blend seamlessly with the sophisticated contours of the case.

Hybrid metal structure – The case is made from a steel frame added with an aluminum motherboard tray and partition plate for a premium touch.

Solid brushed aluminum handles and brushed aluminum covered top and front panels – High quality solid brushed aluminum combines pleasing aesthetics and worry-free transportation.

Airflow optimized design – The whole design follows the COSMOS tradition of providing the best performance, which is why the front and top areas come with high airflow designed mesh.

Stylish and streamlined race-car inspired look – The design has preserved the flagship look to value and respect the COSMOS tradition.

Blue LED ambient lighting – Emphasize the beauty of your components with a discrete blue glow from the LED fan and strip displayed through the tinted tempered glass panels.

Support up to 8 fans and 13 HDDs (2 from X-dock) – Ultra-high fan and disk drive capacity to bolster the high airflow design.
