Cooler Master MasterBox K501L RGB ATX Mid Tower Case

The Cooler Master MasterBox K501L RGB is an ATX mid tower PC case designed for builders who want a balance of aggressive styling, practical cooling capacity, and a showcase tempered glass panel without stretching their budget. The front panel features angled ventilation lines that channel airflow while contributing to the case's sharp, angular aesthetic. Behind the front panel, a pre-installed 120mm RGB LED fan glows through the ventilation cutouts, complemented by an illuminated power button on the I/O panel. A second 120mm fan comes pre-installed at the rear for exhaust, giving the build an active airflow path straight out of the box. The left side panel is a 4mm full-edge tempered glass panel, offering an unobstructed view of the internal components and lighting. The top panel is ventilated and filtered, supporting up to three 120mm or two 140mm fans, while the front and rear positions add further fan support — totalling a maximum of six fan slots across all positions (front, top, rear). Radiator compatibility extends to the front and top positions, accommodating 240mm or 360mm radiators depending on configuration. Cable management is handled by a dedicated routing space of 19–27mm behind the motherboard tray, keeping the visible chamber tidy. The case fits ATX, Micro-ATX, Mini-ITX, SSI CEB, and E-ATX motherboards (E-ATX support limited to 12" x 10.7", which may restrict cable management features). Dust filters are fitted at the top, front, and bottom to reduce particulate ingress.
