Product details

The MasterBox 540 features a vibrant, shimmering design that extends across the entire front panel. Customizable ARGB strips shine behind the transparent facade, creating a stunning play of light. Inspired by automotive lighting design, the front panel houses ARGB light bars paired with a front diffuser. This design element is powered via a pogo pin connection and is seamlessly integrated with the DarkMirror surface of the facade, resulting in unique lighting effects. The ARGB Ether front panel can be controlled either through software or the included ARGB controller, which comes preconfigured with unique lighting presets.
