The MasterBox Q300L is your straightforward alternative in Cooler Master's MasterBox Q series. This series can be compact, yet it stands out for its functionality and modularity without compromising thermal performance. Although its size may not suggest it at first glance, the MasterBox Q300L supports a standard ATX power supply, which is not often seen in this size. Due to various system configurations, the I/O panel can be positioned in six different locations, with three options on each side of the case. You can choose which setup fits your system best. The cubic design of the frame and the unique pattern on the magnetic dust filter will make the chassis stand out from the rest. The combination of practical design and a unique customizable appearance makes the MasterBox Q300L the perfect choice for office and home use.
