The Cooler Master MasterBox 540 is a mid-tower PC case designed with a focus on component visibility and thermal performance. The chassis features a steel frame and a prominent ARGB front panel, which provides customizable illumination that can be managed via an included controller. Its left side is a full panel of tempered glass, secured with a tool-free mechanism for straightforward access to internal hardware. This construction offers a clear view of the build while incorporating materials intended for durability and airflow.
