NOT ALL MESH IS CREATED EQUAL. The MasterBox K Series changed the case industry upon its launch. With an innovative mesh design that filters out dust, refracts light uniquely, and is easy to clean, the K500L set itself apart from the very beginning. Today, the same Fine Mesh spans numerous designs—in the latest Cooler Master cases and even imitated across the industry. Intensively tested by reviewers, Cooler Master’s Fine Mesh proves to the world that providing airflow and dust filtration simultaneously can be achieved. Equal parts performance and aesthetics, the MasterBox K500 ARGB revamps the original K Series with vibrant, out-of-the-box lighting applied to game-changing airflow technology. Sometimes, it takes ingenuity to make a mesh. FINE MESH The Fine Mesh design on the front panel is proven to provide proficient airflow while filtering out dust. Light also refracts and behaves uniquely to the Fine Mesh, creating a halo effect against illuminated components. ARGB LIGHTING SYSTEM Two pre-installed ARGB fans, illuminated accents on the front panel, and an illuminated power button can be managed by either the motherboard or an included controller to create a comprehensive ARGB lighting system. TEMPERED GLASS SIDE PANEL Hardware, custom-loop cooling, and the pure pride of the builder is shown in panoramic view through an edge-to-edge tempered glass side panel. THERMAL PERFORMANCE Airflow is optimized by a collaboration between the Fine Mesh front panel and top panel ventilation. Extra room is provided for optional fans and cooling components for future performance upgrades.
