The MasterBox K-Series changed the case industry upon its introduction. With an innovative mesh design that filters dust, uniquely refracts light, and is easy to clean, the K500L stood out from the very beginning. Today, the same Fine Mesh can be found in numerous designs of the latest Cooler Master cases and is even being imitated throughout the industry. Intensively tested by reviewers, Cooler Master's Fine Mesh demonstrates to the world that it is possible to ensure both airflow and dust filtration simultaneously. The MasterBox K500 ARGB is equally powerful and aesthetically pleasing, revamping the original K-Series with vibrant, ready-to-use lighting and groundbreaking airflow technology. Sometimes it takes ingenuity to create a mesh.
