Despite its small size, this series offers excellent functionality and modularity without compromising on thermal performance. The Master Box Q300L is unique in that it supports a standard ATX PSU, a rare feature for a case of its size.

One of the standout features of the Master Box Q300L is its adjustable I/O panel, which can be positioned in six different locations – three options on each side of the case. This allows you to customize the setup to best fit your system. The cube design of the frame, along with the special pattern on the magnetic dust filter, sets this chassis apart from others on the market.

The Master Box Q300L is the perfect choice for both office and home use, thanks to its practical design and customizable appearance. The magnetic dust filters not only add a unique look to the case but also help keep dust out of your system.

In terms of component clearance, the Master Box Q300L can accommodate CPU coolers up to 159mm in height, GPU cards up to 360mm in length, and PSUs up to 160mm in length. For cooling, you can maximize performance with a 240mm liquid cooler and up to 5 fans.

The modular I/O panel offers flexibility, allowing you to adjust its position on the front, top, or bottom of both sides of the case. The edge-to-edge panel allows you to show off your build with pride through the transparent side panel.

The open thermal design, with perforations on all sides, ensures optimal airflow and heat dissipation. The ample interior space is suitable for Micro-ATX or Mini-ITX motherboards, making expansion easy in the future.

Overall, the Master Box Q300L combines practicality, customization, and performance to make it a standout choice for those looking for a versatile and functional PC case.
