Cooler Master MasterBox MB511 ARGB ATX PC Case (Black)

The Cooler Master MCB-B511D-KGNN-RGA is a mid-tower PC case that blends strong airflow, addressable RGB lighting, and roomy hardware support in a chassis that still fits comfortably on most desks. The front panel uses a fine mesh that channels fresh air straight to the components while holding back much of the dust that tends to collect in gaming systems. If you spend hours chasing high frame rates or rendering large projects, that steady airflow helps the fans stay quiet and the temperatures under control.

Three 120 mm ARGB fans arrive already installed behind the mesh. They connect to an included controller, so you can scroll through colors and effects with a quick button press or hand off control to a compatible motherboard for full lighting synchronization. The glow spills through the front and into the main chamber, giving the build a personal signature without extra cabling.

Inside, the layout welcomes motherboards from Mini-ITX up to E-ATX and leaves 410 mm of clearance for graphics cards. A CPU cooler can stand 165 mm tall, and if you prefer liquid cooling, the frame accepts two 360 mm radiators—one at the front and another on the top panel. In total, seven fan positions are available, so you can expand cooling as hardware demands grow.

A tempered glass side panel swings open to showcase your components and cable routing. Multiple tie-down points and a shrouded power-supply bay make it easier to keep cables out of sight, which also promotes smoother airflow. Removable filters at the front, top, and bottom catch dust before it settles, and they slide out for quick cleaning.

Whether you are building a first gaming rig, setting up a streaming workstation, or refreshing an older tower that runs hot, the MasterBox MB511 ARGB provides space, cooling potential, and subtle style. The exterior wears a black finish that blends into most environments, while the lighting gives the system just the right amount of personality when it powers on.
