Signature Flagship Design
Premium materials including curved aluminum frames from top to bottom and tempered glass panels carry forward the legendary COSMOS identity with a modern upgrade. ARGB under-case lighting further enhances the case’s elegant aesthetic.

Modular Sliding Tray System
Sliding motherboard tray to free up the space inside the case and enable seamless system reconfiguration between air and liquid cooling layouts. Builders can also fine-tune the distance between GPU and side panels with ease – whether to optimize airflow or highlight GPU upfront.

Maximized Compatibility & Clean Layout
Support E-ATX/EEB motherboards, 400mm GPUs, and 240mm PSUs. Includes removable dust filters and 53mm cable clearance behind the tray. Provide builders with uncompromised platform for wide-open FreeForm creation.

Sliding Adjustable Fan Bracket
Fan bracket is adjustable to accommodate case fans in different sizes, and the sliding design allow users to easily move the fans closer to heat spots for better airflow to cool down the system.

Optimized Thermal Architecture
Pre-installed dual extra-thick 200x38mm fans. Accommodate 15 fans at most and support radiator size up to 420mm to ensure ultra-high airflow and versatile cooling flexibility for any build.

Next-Gen Connectivity
Equipped with 4x USB 3.2 Gen1 Type-A 5G & 2x USB 3.2Gen2x2 20G Type-C ports

Thermal & Cooling Excellence
Built to tame the most powerful hardware, the COSMOS ALPHA Gold comes pre-installed with two extra-thick 200x38mm front intake fans and a Mobius 120mm rear exhaust. The sliding adjustable fan brackets allow you to move airflow closer to heat-intensive “hot spots.” With support for up to 15 fans and massive 420mm radiators on the side mount, this case provides the thermal headroom for record-breaking overclocking builds.

Hardware Compatibility
The spacious 140L interior supports E-ATX and EEB motherboards, making it compatible with workstation-class hardware. There is ample room for 400mm GPUs, 186mm tall CPU coolers, and 240mm power supplies. Cable management is effortless with a generous 53mm of clearance behind the motherboard tray and included decorative covers to hide clutter.

Why This Case Is the “ALPHA” Choice
This is more than a case; it is a statement. The combination of rare materials, limited global production, and the most advanced modular sliding system Cooler Master has ever designed makes the COSMOS ALPHA Gold the gold standard for high-end PCs. It is designed for those who refuse to compromise on scale, personalization, or prestige.
