Universal installation. Magnetic dust filters. Viewing window.
The I/O panel can be placed in six different locations. The housing can be placed in a vertical or horizontal position.

A fairly compact Mini-Tower case with an immodestly large potential for assembling a performant and powerful computer. This is a non-standard platform that can be placed both vertically and horizontally. The main feature of the case is the generous perforation of the main covers. The front, top, and rear panels are a solid metal grill protected by an interesting-looking magnetic dust filter.

The platform is adapted for installing a Micro-ATX or mini-ITX motherboard. The maximum length of discrete graphics reaches a record 360 mm for this form factor, and the cooling of the central processor can be implemented with a tower up to 157 mm high. The power supply is mounted at the bottom. The Cooler Master MasterBox Q300L case received a unique viewing sidewall, on which the control panel is located.

The uniqueness of the sidewall is that it can be placed with the control panel up, forward or down, both on the right and on the left. The case comes with one pre-installed 120 mm impeller, the stock cooler is located on the rear panel. In total, the platform has six seats for fans and two mounts for liquid cooling radiators. The case has a cable management system. From the interfaces to the control panel, two USB 3.0 ports and 3.5 mm jacks have been removed. Nearby are the power buttons.

Transformable case

Cooler Master MasterBox Q300L is a compact mini tower case designed for creating both home and gaming computers. The uniqueness of the design is achieved through magnetic dust filters with texture and a flexible modular system. The case can be installed both vertically and horizontally, and the removable control panel allows you to change its position depending on the orientation of the case. The clear acrylic window makes the inside of the case visible, adding to the stylish look and being suitable for placing on a desk. Rubberized feet eliminate vibration and slipping.

Doesn't suffer from modesty

Despite its modest size, the Cooler Master MasterBox Q300L has impressive potential. It is compatible with liquid cooling systems with radiators up to 240mm and supports up to six fans for powerful airflow. The case is suitable for use with graphics cards up to 360mm in length, but the height of the CPU cooler is limited to 157mm. The kit includes one 120mm fan on the rear to exhaust hot air.
