Cooler Master MasterBox Q300L Micro-ATX Tower for Enthusiasts

The Master Box Q300L from Cooler Master is a straightforward option in their new Master Box Series. Although small in size, this series excels in functionality and modularity without compromising thermal performance. Surprisingly, the Master Box Q300L supports a standard ATX PSU, which is not commonly seen in the market for this size. Depending on the system setup, the I/O panel can be adjusted to six different locations, with three options on each side of the case, allowing you to choose the setup that best fits your system.

The cube design of the frame and the unique pattern on the magnetic dust filter make the chassis stand out from the rest. The combination of a practical design and a customizable outlook makes the Master Box Q300L the perfect choice for both office and home use.

The unique pattern of the dust filter adds a distinctive appearance to the case. The case accommodates CPU coolers with a maximum height of 159mm, GPU cards up to 360mm, and PSUs up to 160mm in length. To maximize cooling performance, the case supports a 240mm liquid cooler and up to 5 fans.

The modular I/O panel provides flexibility, as you can adjust its position at the front, top, or bottom on both sides. The transparent side panel allows you to showcase your meticulous build with pride. The perforated design on all sides promotes optimal airflow and heat dissipation, ensuring an open thermal design.

The ample interior space of the Master Box Q300L can accommodate Micro-ATX or Mini-ITX motherboards, making it easy to expand your system in the future.
