PC Midi Tower Cooler Master MasterFrame 600 Mesh Silver — supports ATX/EATX, front 2×200mm, 2.5 inch/3.5 inch drives

The MasterFrame 600 Mesh is a premium modular open-frame ATX mid-tower chassis designed for modular builds, extreme cooling and full customization via the FreeForm 2.0 platform. It supports motherboards from Mini-ITX to E-ATX and provides broad compatibility for high-performance hardware, extensive radiator and fan layouts, and an open exo-structure that enables flexible configurations and maker-driven modifications.

Advantages

The open exo-structure increases adaptability and allows easy reconfiguration of panels and components. Extensive cooling support accommodates up to eleven fans and multiple radiators (up to 420mm) for superior thermal performance. The chassis provides ample GPU clearance up to 485mm and includes a GPU support bracket to prevent sag and ensure stability. Tool-free panel removal simplifies access for upgrades and maintenance, while modular, open-source design files enable personalization and long-term evolution of the build.

How to use

Plan your component layout according to motherboard size and intended cooling configuration before assembly. Mount the selected motherboard (Mini-ITX to E-ATX) to the standoffs, route cables through the open frame for optimal airflow, and install radiators and fans in available mounting positions (supporting up to 420mm radiators). Use the included GPU support bracket to secure long graphics cards and remove panels tool-free for easy access during installation and upgrades. Refer to the FreeForm 2.0 modular files if you wish to modify or replace panels and brackets.

Recommendations

For optimal performance, pair the MasterFrame 600 Mesh with high-flow fans and a 360–420mm radiator for the primary loop. Use the GPU support bracket for heavy or long graphics cards and keep dust filters clean to maintain airflow and thermal efficiency.
