  • Orientation & 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.

    Fully Perforated Chassis

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

    Magnetic Dust Filters

    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.

    Cooling Support

    The bottom supports up to two 120mm fans.
    The rear supports a 120mm fan or 120mm radiator.
    The top supports up to two 120mm/140mm fans or a 120/240mm radiator.

    Storage Support

    Each storage caddy can mount either 2x 2.5" drives or 1x 3.5" drive, two caddies included.
    Possible Configurations:
    4x 2.5" drives | 2x 3.5" drives | 2x 2.5" drives + 1x 3.5" 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.

MasterBox Q500L

Powerful PC build doesn't have to be big in size. Featuring a minimized dimension of mere 386 mm (D) x 381 mm (H), the MasterBox Q500L ATX Mid Tower case can house standard ATX motherboards and PSUs. With versatile positions for I/O panel and PSU and support for versatile 3.5/2.5" drive and fan/radiator combinations, the configuration and layout of your system are full of possibilities. No matter the configuration and layout, the acrylic side window and clean cable management make your system look tidy and clean.
