Cooler Master Expands the MasterFrame Series with the Compact and Modular MasterFrame 400 Mesh

Cooler Master, a global leader in PC components and tech-lifestyle solutions, announced the MasterFrame 400 Mesh, a compact chassis that brings the signature MasterFrame design language to a more accessible, desk-friendly format.

The MasterFrame 400 Mesh delivers FreeForm 2.0 modularity with a simplified build experience. It offers dual orientation (vertical or horizontal), repositionable brackets, and mesh-optimised airflow, enabling builders to tailor layout and thermals with confidence-within a compact footprint that still supports serious hardware.

Engineered for Micro-ATX and Mini-ITX systems, the case accommodates high-performance components without compromise: GPUs up to 390 mm, CPU air coolers up to 190 mm, and extensive cooling headroom with support for up to nine fans and multiple radiators, including top-mounted 360 mm options. A full mesh front panel maximises intake, while a tempered-glass side panel delivers a clean, refined showcase.

Modern connectivity comes standard. Front I/O includes USB 3.2 Gen 2x2 Type-C, dual USB 3.2 Gen 1 Type-A, and a 3.5 mm audio combo jack. A pre-installed SickleFlow 120 mm ARGB fan provides immediate airflow and lighting, helping first-time builders power on with fewer steps.
Connecting FreeForm 2.0 and Thermal Excellence-two of Cooler Master’s core design pillars this yea, the MasterFrame 400 Mesh pairs approachable modularity with generous cooling support. Its mesh-first approach moves more air with fewer obstacles, even in small spaces.
