Cooler Master MasterBox Q300L computer case (black)

The MasterBox Q300L V2 will let you build a PC for everyday tasks. It supports micro-ATX and mini-ITX motherboards and allows you to mount a standard ATX power supply. It allows installation of water cooling and up to 6 120mm fans. In addition, it offers space for 1 HDD and up to 2 SSDs, and with the available ports you will connect additional devices.

Connectors on the top panel

The case is equipped with several ports that will allow you to connect other devices. On the top panel there are 2 USB 3.2 Type A inputs and one USB 3.2 Gen 2x2 Type C. The latter allows data transfer - up to 20 Gbps.

Easy cable management

There is 28 mm of free space behind the motherboard. That's enough to conveniently route all the cables and keep things tidy inside the case. As a result, the computer looks better and has better airflow.

Effective cooling

The case can accommodate up to six fans: two at the front, two at the top, one at the back and one at the bottom. It is also possible to install a water cooler of up to 240 mm. Perforated panels on the front, top and bottom allow air to flow freely.

Glass side panel and easy cleaning

The side panel is made of 4 mm thick tempered glass, through which the components inside can be seen. The panel is mounted with screws that can be easily removed. The case also has an easily removable dust filter.
