MasterBox Q300L Overview
The smaller case out of the two is the MasterBox Q300L, which has official dimension of 387 x 230 x 378mm. This case is all black (currently the only color available) and has a very simple, yet unique look to it.
The thing that gives this case its unique look to it is actually the removable filters on the front and top. Instead of just your normal filters you see on most cases these have a cool design painted on to them. Both of these filters meet at the top front of the case where you’ll find a small Cooler Master logo.
The filters are magnetic filters and easily come off the case. When you remove the filters they reveal large ventilation holes in both the top and front of the case. Seeing this you know the case is going to have airflow. The case officially supports two 120 / 140 mm fans (up to 240 mm radiator) in the front, and two 120 mm fans in the top. You can however install a 240 mm radiator up top, but it will overlap your motherboard.
On the side of the case you’ll find a side panel window. Unlike many of the new cases coming out this panel is not a tempered glass panel, but a normal acrylic panel. It is large enough that you can show off all of your hardware inside and is held into place by four thumbscrews. Also on the side of the case you’ll find all of your connections and buttons. You have two USB 3.0 ports, a large power button, HD audio connections, and a small reset button. One thing that is cool about this control panel is that it can be moved to all four sides of the side of the case as the side panel can be positioned anyway that you like.
The opposite side panel is plain, but it does have four thumbscrews on it making it very easy to remove. You can actually swap the side panels if you really wanted to and install the control panel on the rear of the case.
At the rear of the case we have a pretty basic design where we can see where our Micro-ATX motherboard will be mounted, some ventilation where there is a 120 mm fan mounted (this is the only included fan with the Q300L), and the power supply mount on the bottom.
Flipping the case over to the bottom there are four rubber feet that keep the case off the ground and there is a filter the runs across the entire length of the case.
