At CES 2026, Cooler Master showed off its latest PC cases from the COSMOS and MasterFrame lines, along with a range of matching add-ons. The high-end COSMOS series now includes the new COSMOS Alpha case. It is built using a modular design, curved aluminium frame and tempered glass side panels. One of its standout features is a sliding motherboard tray, which allows the internal layout to be adjusted for cleaner airflow or liquid-cooling-focused builds. Cooler Master also includes a sliding, adjustable fan bracket that supports multiple fan sizes. COSMOS Alpha can house E-ATX and EEB motherboards in addition to ATX and microATX, graphics cards up to 400 mm long, and power supplies up to 240 mm. Cooling support includes up to 15 fans, with dual pre-installed 200 × 38 mm extra-thick fans, removable dust filters, and radiators up to 420 mm.

Cooler Master also expanded its open-frame MasterFrame lineup with the new MasterFrame 360 series, built around a 360-degree display concept. The series includes three variants: MasterFrame 360 Panorama, a sealed tempered-glass enclosure designed for full visibility and protection; MasterFrame 360 Stage Mirror, an open-frame design with a mirrored base to enhance visual depth; and MasterFrame 360 Stage LCD, which integrates a 15.6-inch display for custom visuals or use as a secondary screen.
