PC Case Cooler Master MasterFrame 500 Mesh Midi Tower — Black with Transparent Side, supports ATX/EATX, 2x200mm front, 1x120mm rear

The Cooler Master MasterFrame 500 Mesh is a premium open-frame mid-tower PC case built for modular builds, advanced cooling and broad customization via the FreeForm 2.0 platform. It supports Mini-ITX to E-ATX motherboards and accepts ATX power supplies, with a tempered-glass transparent side and enhanced mesh panels to improve airflow. The chassis ships with two 200 mm front fans and one 120 mm rear fan preinstalled and includes a GPU support bracket to prevent GPU sag during heavy use.

Advantages

The open-frame FreeForm 2.0 exo-structure offers flexible configuration options and direct access to modular design files for maker-driven personalization. Tool-free panel removal simplifies assembly and upgrades, while support for multiple motherboard sizes and extensive cooling options (up to eight fans and various radiator sizes, including up to 360 mm) ensures compatibility with high-performance components. Materials include tempered glass, SGCC and aluminium for a balance of durability and visual clarity.

How to use

Install the selected motherboard (Mini-ITX to E-ATX) and ATX power supply into the chassis following the provided mounting points. Use the tool-free panels to access the interior for component installation and routing. Mount storage in the 3.5"/2.5" combo cage and secure the GPU using the included GPU support bracket. Configure fans and radiators according to your cooling plan—the case supports up to eight fans and multiple radiator sizes for custom air or liquid cooling setups.

Recommendations

For optimal airflow, keep mesh panels unobstructed and use a balanced fan configuration (intake at the front, exhaust at the rear/top). When installing large radiators or E-ATX motherboards, verify clearance for GPU length and cable routing before final assembly.
