COSMOS ALPHA Enthusiast RGB Full Tower from Cooler Master
The Future is NowTwisting dimensions and conventions, the COSMOS ALPHA combines a curved aluminium frame, tempered glass panels, and under-case lighting with a fully reconfigurable interior that moves with you. Dual fold-out doors reveal a futuristic rail-based system where the motherboard tray and fan brackets freely slide into position, letting you reshape airflow, showcase hardware, or switch between air and liquid cooling without tearing the build apart. With support for E-ATX/EEB platforms, 400 mm GPUs, up to 15 fans, and radiators reaching 420 mm, the ALPHA delivers serious thermal capacity inside its striking, spaceship-like structure not quite from this world.
Designed to Innovate
FreeForm 2.0The COSMOS philosophy has always been about transcending limits of what a PC case should be, and the COSMOS ALPHA carries that forward as a true “halo” platform for builders who want complete control.
It carries forward the signature curved aluminium form while evolving FreeForm 2.0 into something more deliberate — every internal component can rotate or flip, turning layout into a choice rather than a constraint. This is where scale, modularity, and personal expression meet, giving builders the freedom to shape not just a PC, but their own interpretation of it.
Modular Sliding Rail System
Movable Fan BracketsFan brackets don’t just sit in place — they slide along rails, letting you shift cooling closer to GPUs, radiators, or hotspots as your hardware demands. It gives you direct control over airflow placement, turning cooling from a fixed setup into something you can actively adjust.
Sliding Motherboard TrayThis modularity extends to the motherboard tray, which slides to change how space is allocated inside the chassis. You can push it to open up clearance for larger cooling setups or pull it in to tighten the layout and bring components into focus. It makes switching between air and liquid cooling layouts far more practical.
Optimised Thermal Architecture
Fan CompabilityCooling starts strong with a pre-included pair of 200mm intakes and a 120mm exhaust fan, delivering high airflow straight out of the box. The case scales far beyond that baseline though, supporting up to 15 fans across front, top, rear, bottom, and side mounts, with compatibility spanning 120 mm, 140 mm, 180 mm, and 200 mm sizes to suit a wide range of airflow strategies.
Radiator ClearanceRadiator support matches that flexibility, with up to 360mm supported on both the top and bottom, with expanded capacity on the side mount with support for 420 mm or even triple 360 mm configurations. This gives builders the space to deploy colossal multi-radiator liquid cooling setups, with enough clearance to handle thicker radiators where needed.
Control Over Clearance
From ITX to EEBCOSMOS ALPHA is ready to take on most hardware you throw at it, providing standoffs and space for mini-ITX, microATX, ATX, E-ATX and SSI-EEB motherboards on the sliding tray.
53 mm of cable routing space behind the tray keeps everything clean as configurations evolve. Support for GPUs up to 400 mm and ATX PSUs sets the foundation for past, present and future components.
A branded, solid metal support bar guides your GPU along the case seamlessly as well, allowing you to tighten it in place to whichever degree feels right.
