Modular ATX Case with Reversible I/O

The Cooler Master QUBE 540 is a mid-tower chassis built from steel and tempered glass in a Stardust Iron finish. It supports ITX, M-ATX, ATX and E-ATX boards up to 280 mm wide. A movable I/O panel and portable handles let you run the case horizontally or vertically while keeping ports accessible.

Builders Who Want Layout Freedom.

This case suits enthusiasts who value flexible orientation, 3D-printable customisation and a full-mesh front for airflow. It is less suited for users who need more than one 3.5-inch bay or more than two 2.5-inch bays, or who require a front panel that stays fixed in one position.

415 mm GPU Clearance Decides Fit for Large Cards

The single spec that determines whether this chassis works for your build is the maximum graphics card length of 415 mm. Measure your card; if it exceeds this figure you must choose a different case. The limit applies when no front fan is installed.

Questions about this item

Does the QUBE 540 include the 3.5-inch and 2.5-inch drive trays I need for my existing storage drives?

The chassis provides one internal 3.5-inch bay and two internal 2.5-inch bays, so your current drives will fit directly.

Will my ATX motherboard that is 11 inches wide fit in this case?

The QUBE 540 supports E-ATX boards up to 280 mm wide, covering standard 11-inch ATX and larger E-ATX models.

How can I confirm the pre-installed Sickle Flow 120 mm fan is running after I build the system?

Connect the fan to a motherboard header, power on, and verify RPM in BIOS or fan-control software; the front mesh panel should show clear airflow.
