Cooler Master Shrinks the MasterFrame Into the 400 Mesh

The new MasterFrame 400 Mesh pushes Cooler Master deeper into the modular case space with a compact frame that still feels like part of the MasterFrame family. This smaller chassis keeps the open-air, customizable spirit alive in a desk-friendly format.

Compact Layout With Serious Hardware Support

Despite its reduced footprint, the MasterFrame 400 Mesh still welcomes Micro-ATX and Mini-ITX hardware. Builders also get GPU clearance up to 390 mm and CPU cooler support up to 190 mm, making full-size components viable in a compact form.

FreeForm 2.0 Modularity Made Accessible

This case carries the FreeForm 2.0 philosophy with vertical or horizontal configurations. Its repositionable brackets and mesh-driven airflow layout give users flexibility to adjust layout and thermals with ease.

Cooling Headroom With Mesh-First Airflow

A full mesh front panel anchors the thermal design, supported by up to nine fans and multiple radiators including 360 mm options. A pre-installed SickleFlow ARGB fan provides instant airflow and lighting for a smoother first-time build.

Showcase-Ready Aesthetics and Modern I/O

The tempered glass panel keeps the interior visible, while premium aluminum accents add polish. Connectivity is modern with USB 3.2 Gen 2×2 Type-C, dual USB 3.2 Gen 1 ports, and a 3.5 mm combo jack for everyday setups.

Conclusion

The MasterFrame 400 Mesh delivers modular freedom in a smaller, more approachable frame. It blends airflow and compatibility with a clean showcase design, making it an easy entry point into the MasterFrame family. Cooler Master will offer it in Silver and Black, with pricing and availability varying by region.
