    Cooler Master

    Choose Your Style

    The MasterBox Q300L is your straightforward option in the MasterBox Q-series from Cooler Master, a series that might be small in size but excels in functionality, modularity, and thermal performance.

    Cooler Master

    System Flexibility

    The I/O panel can be adjusted to six different locations—on both side of the body you can install the I/O panel at the front, top or bottom.

    Cooler Master

    Magnetic Dust Filters

    Patterned magnetic filters create a unique look for your chassis while keeping your system's internals free from excess dust.

    Cooler Master

    Small Form Factor, ATX PSU Support

    Despite the Micro-ATX form factor and the body depth/height of only 370 x 370mm, the MasterBox Q300L can accommodate a normal ATX PSU.

    Cooler Master

    Edge-to-Edge Acrylic Side Panel

    Show off your build through the full size transparent side panel.

    Cooler Master

    Thermal Performance

    The open design of the perforated front, top, and bottom guarantees excellent thermal performance.

    Cooler Master

    Routing Space

    A space 28mm-wide behind the motherboard tray offers open space for hidden cable management.

    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.
