The Cooler Master's all-new Master Box Series features the straightforward Master Box Q300L as your go-to option. This series may be small in size, but it excels in functionality and modularity without sacrificing thermal performance. Surprisingly, the Master Box Q300L supports a standard ATX PSU, which is uncommon in the market for a chassis of this size.

Depending on your 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 configuration that best suits your needs. The cube design of the frame and the unique pattern on the magnetic dust filter give the chassis a distinctive appearance that sets it apart from the rest.

The combination of a practical design and a customizable outlook make the Master Box Q300L the perfect choice for both office and home environments. The unique pattern of the dust filter adds a distinctive touch to the case's appearance.

The Master Box Q300L offers ample components clearance, accommodating CPU coolers up to 159mm in height, GPU cards up to 360mm, and PSUs up to 160mm in length. To maximize cooling performance, the chassis supports a 240mm liquid cooler and up to 5 fans.

The modular I/O panel provides flexibility, allowing you to adjust its position at the front, top, or bottom on both sides of the case. The edge-to-edge transparent side panel showcases your meticulous build with pride.

Designed for optimal airflow and heat dissipation, the perforated design on all sides of the chassis promotes an open thermal design. The ample interior space ensures easy and future expansion, supporting Micro-ATX or Mini-ITX motherboards.

In conclusion, the Cooler Master Master Box Q300L is a versatile and customizable chassis that combines a practical design with a unique appearance, making it the perfect choice for both office and home setups.
