Key Features

PATTERNED MAGNETIC DUST FILTERS - The custom-designed front and top magnetic dust filters are completely removeable and present a sophisticated, yet cunningly minimalist, functional chassis facade.

VERTICAL OR HORIZONTAL- The MasterBox case features rubberized thumbscrews that enable either a standing or laying orientation with fully-perforated panels for multiple airflow configurations.

MULTIPLE COOLING OPTIONS - The front panel can support up to two 140mm fans or a 240mm liquid cooler radiator. The rear panel supports a 120mm cooling module (fan or radiator), while the top can house two 120mm fans.

EDGE-TO-EDGE DISPLAY - The square edge-to-edge transparent side panel enables a full display of any system build, and includes an I/O panel which can be rotated into 3 different orientations on either side. Behind the motherboard tray is 28mm of allocated space for clean cable management.

SPACIOUS INTERIOR - The MasterBox Q300L supports CPU coolers up to a height of 159mm, graphics cards (GFX) up to a length of 360mm, and power supplies (PSU) up to 160mm in length.
