Cooler Master Cases

Cooler Master has been making cases for a long time, and the ranges divide by priority.

Elite is the value line — plain, compact, inexpensive chassis in mini tower and midi sizes, which is exactly right for an office build or a first PC. MasterBox is the mainstream range, with mesh and tempered-glass options across micro-ATX and ATX. HAF (High Air Flow) is the airflow-focused line, and Cosmos the flagship.

The question worth asking of any case is airflow versus appearance. A mesh or well-vented front lets intake fans pull cold air straight onto the components; a solid glass front restricts it. If you are running a warm processor or a large graphics card, favour mesh — the difference in temperature and noise is larger than any other case feature.

Before ordering, check three numbers against the specification: graphics card length, CPU cooler height, and radiator size if you plan on liquid cooling. Those end more builds than anything else.
