Fully Perforated Chassis w/ Magnetic Dust Filters

The top, front, rear, and bottom panels are fully perforated to support various fan configurations.

The magnetic dust filters feature a unique design. Magnets allow for quick removal and installation for easy cleaning of the dust filters with rubber stompers to keep the filters from sliding.

Modular Orientation w/ A Movable I/O Panel

The modular MasterBox Q500L can orient vertically and horizontally with rubberized thumbscrews that also act as feet. Depending on hardware configuration, the movable I/O panel can be relocated to multiple positions to retain its accessibility.

Versatile PSU Bracket

The PSU bracket enables the PSU to adapt to different clearance requirements and motherboard form factors. The PSU bracket can shift up or down for top radiator/graphics card clearance and can also be relocated for ITX systems.


Edge-To-Edge Transparent Side Panel

The side panel displays system builds in full view.

  • The top supports up to two 120mm / 140mm fans or a 120 / 240mm radiator

  • 2x 3.5in Drives
  • 2x 2.5in Drives + 1x 3.5im Drive

Motherboard Support

The internal layout and PSU location adapts to the motherboard.

If a standard ATX motherboard is used, the PSU mounts to the top-front of the chassis with the ability to shift upward or downward.

For mini-ITX builds, the PSU can be located in the conventional bottom-rear position for increased front panel ventilation.

Clean Routing Space

Behind the motherboard tray, 27~30mm width of space is offered for cable management with the entire perimeter dedicated as a channel for cables.
