The Next-Generation Design: Back-Connected Motherboard Support

One of the most revolutionary features of the MasterBox 600 is its support for back-connected motherboards.⁵ This innovative design, compatible with the latest motherboards from brands like ASUS (BTF), MSI (Project Zero), and Gigabyte (Stealth), completely redefines cable management.⁶ Instead of routing cables through the front of the case, all power, SATA, and fan headers are located on the back of the motherboard.

This means a dramatic reduction in cable clutter within the main compartment. The result is a pristine, unobstructed view of your components through the tempered glass side panel, as well as a significant improvement in airflow. With all cables tucked neatly behind the motherboard tray, the interior of your PC becomes a clean canvas, showcasing your hardware in its best light.

A Closer Look: Technical Specifications of the MasterBox 600

The power of the MasterBox 600 lies in its detailed specifications, which are a testament to its performance-oriented design.

Chassis and Dimensions

The case features a robust construction of steel, plastic, and tempered glass. Its dimensions, 474 x 230 x 481mm (including protrusions), provide a spacious interior that easily fits within most setups while offering ample room for components.⁷ The 49.73L volume is expertly utilized to create a highly efficient internal layout.

Motherboard and Component Compatibility

The MasterBox 600 offers exceptional compatibility, supporting a wide range of motherboard form factors, including ITX, Micro ATX, ATX, and E-ATX (up to 12″ x 10.9″). This versatility allows for a broad spectrum of builds, from compact powerhouses to expansive workstations.

The clearances are equally impressive. It supports CPU coolers up to 170mm in height and graphics cards up to 410mm in length (without a front radiator, or 360mm with a front radiator). This ensures compatibility with virtually all high-end components on the market today.

Storage and I/O

The case provides flexible storage options with two dedicated 3.5″ drive bays and two 2.5″ drive bays (with support for up to six 2.5″ drives).⁸ The included removable HDD cage further enhances flexibility, allowing for improved access during assembly and system upgrades.⁹

The front I/O panel is conveniently located and features two USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 2×2 Type-C port, and a 3.5mm combo audio jack.¹⁰ The inclusion of a high-speed USB Type-C port is a standout feature, providing future-proof connectivity.

Unrestricted Airflow and Cooling Performance

The MasterBox 600 is designed from the ground up for superior thermal performance. The FineMesh performance front panel allows for unrestricted airflow, pulling cool air directly into the system.¹¹

The case comes with four pre-installed ARGB fans, offering exceptional cooling out of the box. This includes three 140mm SickleFlow 140 ARGB PWM fans in the front and a single 120mm CF120 ARGB fan at the rear.¹² These fans not only provide powerful airflow but also brilliant, customizable lighting.

For those who want to take cooling to the next level, the case offers extensive support for both air and liquid cooling. You can install a total of up to seven fans, with fan support in the front, top, and rear. For liquid cooling, the MasterBox 600 supports a massive 420mm radiator at the front and a 360mm radiator at the top, allowing for hyper-effective CPU and GPU cooling.¹³

Key Benefits of the MasterBox 600

Choosing the MasterBox 600 offers a multitude of benefits that translate directly into a better building and ownership experience.

1. Simplified Cable Management

The back-connected motherboard support is a game-changer for cable management. By moving all the cables behind the motherboard tray, it eliminates clutter, improves aesthetics, and dramatically simplifies the building process.¹⁴ Even with a traditional motherboard, the ample 33-35mm of space behind the tray provides plenty of room to hide cables, preventing the dreaded “side panel bulge.”¹⁵

2. Enhanced Thermal Performance

The combination of the FineMesh front panel and the four pre-installed, high-performance fans ensures your system runs cool and quiet.¹⁶ Better airflow means less thermal throttling, which is crucial for maintaining peak performance during intense gaming sessions or heavy workloads.

3. Unrivaled Aesthetics

The clean, uncluttered interior, combined with a tempered glass side panel and vibrant ARGB fans, makes the MasterBox 600 an ideal showcase for your components.¹⁷ You can build a PC that not only performs brilliantly but also serves as a visual centerpiece for your desk.

4. Future-Proof and Versatile

With support for a wide range of motherboards, large GPUs, and extensive cooling options, the MasterBox 600 is built to last. You won’t need to replace your case with every hardware upgrade. The removable HDD cage and generous clearances provide the flexibility to adapt your build as your needs evolve.¹⁸

5. Premium Features at an Accessible Price

Cooler Master has packed the MasterBox 600 with premium features that are typically found in more expensive cases. From the back-connected motherboard support to the pre-installed ARGB fans and the versatile cooling options, this case offers exceptional value, making a high-end PC build accessible to a wider audience.¹⁹

The Building Experience: Designed for You

Building a PC in the MasterBox 600 is a pleasure. The design focuses on ease of use and accessibility. The tool-free tempered glass panel makes it easy to access your components. The spacious interior provides plenty of room to work, reducing the frustration of cramped spaces. The pre-installed fan hub and well-placed cable routing channels simplify the wiring process.

The removable HDD cage is another thoughtful detail, allowing you to free up space for a longer PSU or better cable management if you don’t need the extra drive bays. Every aspect of the case’s design has been considered to make the building process as smooth and enjoyable as possible.
