PC Midi Tower Cooler Master MasterFrame 500 Mesh — Black with Transparent Side, supports ATX PSU, 2x200mm front + 1x120mm rear, 2.5 inch/3.5 inch drives

The Cooler Master MasterFrame 500 Mesh is a premium open-frame mid-tower chassis designed for modular builds, advanced cooling setups, and extensive customization via the FreeForm 2.0 platform. The case supports motherboards from Mini-ITX up to E-ATX and includes mesh panels and a transparent side for improved airflow and component visibility. Factory cooling comprises two 200 mm front fans and one 120 mm rear fan; the front panel accepts multiple fan diameters and radiator sizes to accommodate airflow-focused gaming and workstation builds.

Advantages

The open-frame FreeForm 2.0 exo-structure provides flexible configuration options and easy access for modifications. Tool-free panel removal simplifies assembly and upgrades. Mesh panels and included large-diameter fans enable enhanced airflow, and an included GPU support bracket prevents GPU sag for a stable installation. The interchangeable, maker-driven design allows for personalization and integration of custom parts.

Suitable for

• Airflow-focused gaming PCs

How to use

Install the chosen motherboard (Mini-ITX to E-ATX) onto the open-frame tray and secure the power supply in the designated ATX location. Mount storage drives into the 2.5"/3.5" combo cage and install the GPU with the included support bracket to prevent sag. Use the tool-free panels for quick access during component installation or maintenance. Configure fan and radiator placements according to your cooling plan, using the front panel for large-diameter fans or radiators and the rear for exhaust.

Recommendations

For optimal thermal performance, use the front panel with 200 mm fans or a 360 mm radiator paired with rear exhaust; ensure adequate clearance for E-ATX builds and route cables to maintain unobstructed airflow.
