CHOOSE YOUR STYLE

The MasterBox Q300L is your straightforward option in the
lineup of the brand new MasterBox Q-series from Cooler
Master. A series that might be small in size but excels in
functionality and modularity without compromising on the
thermal performance.

Although the size wouldn’t tell, the MasterBox Q300L
supports a standard ATX PSU which we don’t see often in
the market with this size. Based on the different system
setup, the I/O panel can be adjusted to six different
locations, three options at each side of the case. You can
decide which setup fits your system best.

Due to the cube design of the frame and special pattern
design on the magnetic dust filter will make the chassis
stand out from the rest. The combination of a practical
design and the unique customizable outlook makes the
MasterBox Q300L the perfect choice for office and home
usage.
