Cooler Master Launches the MasterFrame 700, an Open-Air PC Case that transforms into a Test Bench

LOS ANGELES, CALIFORNIA Cooler Master today launches the MasterFrame 700, a customizable frame that can convert between an open-air showcase PC chassis or a highly-flexible test bench.

The MasterFrame 700 is a must-have for enthusiastic PC tinkerers. Designed for custom-loop water-cooling experimentation, testing hardware on-the-fly, and showing off oversized components through panoramic tempered glass, the potential for customization is limited only by imagination.

Two Modes, Three Parts, No Limits

The MasterFrame 700 features a 3-part design consisting of two side wings and a fully-featured motherboard tray. Four specially-designed friction hinges hold the side wings to the motherboard tray, allowing both full range of motion during assembly and stability when built, perfect for custom water-cooling loops.

Transformation between an open-air PC case and test bench is achieved through the modular wings. In open-air mode, the MasterFrame 700 stands vertically to best display the components behind its panoramic tempered glass screen. The chassis offers an unmatched level of hardware compatibility, allowing for easy-fitting of oversized components. The wings fold forward, stabilized with rubber feet, to ensure all components are captivatingly displayed.

In test bench mode, the side wings fold down towards the CPU socket and graphics card area to allow for localized airflow to the components—especially useful when overclocking. The wings also serve as spots to hold triple-fan radiators and other accessories, and thanks to their full range of mobility, swapping components while keeping the cooling solution in place is now easier than ever. While oriented as a test bench, mounting capabilities are increased to support 3 x 360mm radiators simultaneously.

The MasterFrame 700 can be easily customized with its teardown-friendly design. Every component can be disassembled for custom paint jobs, vinyl wrap, and any other modifications the community may think of. For PC tech artists and hardware junkies alike, the MasterFrame 700 is a canvas unrivalled in functionally, design, and value.


Premium Variable Friction Hinges – Heavy duty hinges hold the side wings to the mid-frame and allow for smooth repositioning at any angle depending on the user’s needs. Allen keys are included to adjust the tension of the hinges to make it easier to move or allow the side wings to hold heavier parts. This level of flexibility is a key factor for users creating extremely unique water-cooling loops and setups.

Open Air Design – The open-air nature of the design provides unrestricted access to fresh air to all components in the system. The optional fan mounts allow to further guide the airflow path to a specific intake/exhaust direction, thus preventing performance-robbing heat recirculation. Unmatched Hardware Support - For its size, MasterFrame 700 sports an unmatched level of hardware compatibility. It is designed to fit any component available, even oversized ones. Users can mount up to SSI-EEB motherboards, multiple power supplies and multiple radiators at the same time and still have room for triple slots GPUs and storage.

Extreme Water-Cooling Support - Designed with water-cooling in mind, MasterFrame 700 provides a flexible pump and reservoir mounting location and support for multiple triple-fan radiators.

Test Bench Mode – Thanks to its modular design, MasterFrame 700 can lay down horizontally and transform into an ultra-featured premium Test Bench. Cooling and power components are installed out of the way of the motherboard area for interference-free installation of components.

Panoramic Tempered Glass – The oversized panoramic tempered glass offers a greater viewing angle on the components of the system and, together with hardware-centric design of MasterFrame 700, it is the perfect way to showcase high-end components and custom cooling solutions.

VESA Mount Compatible – The MasterFrame 700 features 100mm x 100mm VESA mount compatibility, allowing it to be wall-mounted. Perfect to showcase custom loops and high-end components. It is highly recommended to only wall mount full systems below 14Kg in total and check VESA weight standards.

Designed For Customization – The MasterFrame 700 is designed with customization in mind. The 3-parts frame can be easily disassembled easily for painting, wrapping and other modifications.


The MasterFrame 700 will be available for £179.99
