Overview



COSMOS ALWAYS LEADING
COSMOS series, hailed as the ultimate expression of PC case modularity, evolves into the “halo” platform for enthusiasts and modders. With its iconic design language and enhanced modular internals, COSMOS is engineered for boundary-pushers who want limitless control over layout, cooling, and customization.

Brand new COSMOS ALPHA will serve as the aspirational apex of what FreeForm 2.0 stands for — freedom, scale, and personalization without compromise, making it an ALPHA case for all ALPHA builders

Sliding Motherboard Tray
Sliding tray design 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

Sliding Adjustable Fan Bracket
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

Maximized Compatibility & Space
Support E-ATX/EEB motherboards, 400mm GPUs, and 240mm PSUs. Tool-free bays support up to 7 drives for effortless expansion. Provide builders with uncompromised platform for wide-open FreeForm creation.
