Compact and powerful
The MasterFrame 400 Mesh is specially designed for users looking for a compact case with high functionality. It offers space for graphics cards up to a length of 390 mm and CPU air coolers with a height of up to 190 mm.
Despite its compact dimensions, the case creates space for up to nine fans and multiple radiators, including a 360 mm option at the top for efficient heat dissipation. The front mesh panel maximizes fresh airflow, while the tempered glass side panel allows for an elegant presentation of the installed hardware.
Flexible construction and modern design
Modularity is a key feature of the MasterFrame 400 Mesh. The FreeForm 2.0 Exo structure made of aluminum ensures stability and enables flexible configurations. Thanks to the dual orientation, users can set up the enclosure either vertically or horizontally, allowing it to be optimally adapted to the workplace. The brackets can also be repositioned to enable different layouts. Options for modern I/O include USB 3.2 Gen 2×2 Type-C, two USB 3.2 Gen 1 Type-A ports and a 3.5 mm combo jack. A pre-installed SickleFlow 120mm ARGB fan makes it easy to get started with instant cooling performance and lighting.
Style and availability
Visually, the case impresses with high-quality aluminum accents, rounded edges and a clear look thanks to the side window. It is available in two colors: silver and black. With a recommended retail price of around 149 euros, the MasterFrame 400 Mesh will be available in Europe from January 2026, although the exact date varies depending on the country.
The MasterFrame 400 Mesh is therefore an ideal choice for gamers, content creators and PC hobbyists looking for a compact, yet powerful and well-ventilated case that can be flexibly adapted to individual needs.
