Cooler Master Q500L MCB-Q500L-KANN-S00

Cooler Master MasterBox Q500L

Full ATX Power. Micro-ATX Footprint. The Cooler Master MasterBox Q500L is a revolutionary chassis that defies traditional size constraints. By utilizing a highly innovative internal layout—specifically an adjustable, front-mounted power supply bracket—this case is capable of housing a standard ATX motherboard within a footprint normally reserved for much smaller Micro-ATX builds. Featuring a fully perforated chassis, magnetic dust filters, and a modular I/O panel, the Q500L offers builders unprecedented flexibility and high-end thermal performance in an ultra-compact package.

Key Features

• Standard ATX in a Compact Body: Maximize your desk space without sacrificing hardware compatibility. The Q500L supports standard ATX motherboards and full-sized ATX power supplies despite measuring only 381mm in height and 386mm in length.

• Fully Perforated Chassis: The top, front, bottom, and rear panels are fully perforated to ensure unrestricted airflow. This highly breathable design guarantees that your internal components receive massive amounts of fresh air from almost every angle.

• Movable I/O Panel: The modular I/O panel can be relocated to multiple different positions on the chassis. Depending on your setup and preference, it can be mounted on the top, bottom, or front edge of the side panel for easy access.

• Vertical and Horizontal Orientation: The case is designed to be highly adaptable to your workspace. Rubberized thumb screws on the side panel double as feet, allowing the Q500L to be laid completely flat horizontally or stood up vertically as a traditional tower.

• Adjustable PSU Bracket: The innovative power supply bracket allows the PSU to be mounted at the front of the case to make room for the ATX motherboard. The bracket can shift up or down depending on the length of your graphics card or the size of your liquid cooling radiator.

• Magnetic Dust Filters: The top and front panels feature unique, patterned magnetic dust filters. They add a striking visual geometric element to the case while keeping dust out and being incredibly easy to peel off and clean.

• Edge-to-Edge Transparent Side Panel: A full-sized, transparent acrylic side panel provides a clear view of your custom build, allowing you to show off your motherboard, GPU, and internal lighting effects.
