The Cooler Master Master Box Q300L is a straightforward option in the brand new Master Box Series. This series may be small in size, but it excels in functionality and modularity without compromising on thermal performance. Although its size might not suggest it, the Master Box Q300L supports a standard ATX PSU, which is not commonly seen in the market with this size.

Based on the different system setup, the I/O panel can be adjusted to six different locations, with three options on each side of the case. This allows you to decide which setup fits your system best. The cube design of the frame, combined with the special pattern design on the magnetic dust filter, make the chassis stand out from the rest. The combination of a practical design and the unique customizable outlook makes the Master Box Q300L the perfect choice for office and home use.

The unique pattern of the dust filter adds a distinctive appearance to the case, while the components clearance accommodates CPU coolers with a maximum height of 159mm, GPU cards up to 360mm, and PSU 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 offers the flexibility to adjust its position at the front, top, or bottom on both sides, allowing you to tailor the setup to your preference. The edge-to-edge panel showcases your meticulous build through the transparent side panel with pride. The perforated design on all sides promotes optimal airflow and heat dissipation, ensuring an open thermal design.

Lastly, the ample interior space accommodates Micro-ATX or Mini-ITX motherboards, allowing for easy and future expansion of your system.
