Cooler Master expands MasterFrame lineup with compact 400 Mesh chassis

Cooler Master has announced the MasterFrame 400 Mesh, a compact PC case designed for Micro-ATX and Mini-ITX builds. The chassis brings the company’s modular MasterFrame design to a smaller format, emphasising airflow and flexible orientation.

The case supports vertical or horizontal layouts, with repositionable brackets to adapt to different setups. Despite its reduced footprint, it accommodates full-size components, including graphics cards up to 390mm long and CPU air coolers up to 190mm tall. Cooling options are extensive, with room for up to nine fans and multiple radiators, including 360mm units mounted at the top. A mesh front panel maximizes intake, while a tempered-glass side panel provides a clear view of hardware.

Connectivity includes USB 3.2 Gen 2×2 Type-C, dual USB 3.2 Gen 1 Type-A ports, and a 3.5mm audio combo jack. A SickleFlow 120mm ARGB fan comes pre-installed, offering basic airflow and lighting out of the box. The case will be available in silver and black finishes, with aluminum accents and curved edges rounding out the design.

Cooler Master positions the MasterFrame 400 Mesh as the most accessible entry in the MasterFrame lineup, aimed at builders who want modularity and airflow in a smaller footprint.

The MasterFrame 400 Mesh launches in Europe starting January 2026, with rollout varying by country. Pricing is set at €149.
