PC Case Cooler Master MasterBox 600 Desktop Black

The Cooler Master MasterBox 600 is a mid-tower desktop PC case designed for effective airflow and flexible component installation. It supports ATX, Micro ATX, ITX and EATX motherboards, offers space for long graphics cards and large radiators, and includes multiple fan mounting positions and drive bays to accommodate most modern builds.

Advantages

The MasterBox 600 provides space for a 420mm front radiator and a 410mm graphics card, plus support for a 170mm CPU cooler. A fine-mesh front panel and supplied fans ensure improved airflow and thermal performance. The back-connected motherboard layout increases cable-routing space behind the motherboard tray (around 33–35 mm) to simplify cable management. The removable HDD cage and multiple 2.5"/3.5" drive mounting options make installation and upgrades easier.

Suitable for

• Gaming PCs with large GPUs (up to 410 mm)
• Air- and liquid-cooled systems using up to 420 mm front radiators
• Tool-free builds requiring good cable management and drive flexibility
• Compact workstations that still need support for EATX/ATX motherboards

How to use

Install the chosen motherboard on the included standoffs and route cables through the rear cutouts, using the increased 33–35 mm space behind the tray for tidy cable management. Fit the power supply in the designated compartment and mount storage drives in the removable HDD cage or dedicated 2.5" mounts. Place the GPU (up to 410 mm) into the PCIe slots and secure it. Configure cooling by installing radiators or fans in the front and top mounts as required; the case supports multiple fan configurations and radiators up to 420 mm in front and 360 mm on top.

Recommendations

For best thermal results, use the fine-mesh front panel with front intake fans and a rear exhaust fan. If installing a large front radiator, verify clearance for front-mounted drives and consider removing the HDD cage for additional space. Use the back-connected motherboard routing to keep airflow unobstructed and maintain tidy cable runs.
