A modern gaming case with a compact chassis, positioned by the manufacturer in an affordable price segment. The model is compatible with micro-ATX motherboard. The façade uses an enlarged ventilation duct. The main mesh surface is complemented by a side sheathing. To optimize airflow, two front fans with PWM and ARGB are used. Automatic adjustment of the turntable speed allows you to make the PC low-noise.

At the same time, air cooling performance always remains at its best. The gaming computer case Cooler Master MasterBox MB311L ARGB uses a HDD basket with convenient removable slides, two 3.5" slots, and additionally there are anti-vibration spacers for mounting two 2.5" drives. The rear panel with PCIe slots has four single-use brackets. Such slots break out. The mesh facade has an easily removable fixation. Instead of wired connection of interfaces and buttons, contact plugs are provided. When you disconnect the front cover, you don't have to worry about any of the connections accidentally coming loose. A well-ventilated lid with a filter mesh on a flexible magnetic frame is installed on top. In the upper part you can mount a liquid cooling system based on a 240 mm radiator.
