C700M 30th Anniversary


COSMOS C700M 30th Anniversary

The COSMOS series is known for pushing the limits of Cooler Master’s case technology. The freedom in layout organization and the support for unique graphics card mounting make custom building accessible as soon as the COSMOS C700M is unboxed.

The idea is to inspire growth in builders across all levels—since the chassis is only as complex as builders need it to be, there will always be room to creatively experiment. If modders decide to take customization even further, the COSMOS frame allows for sandbox-level versatility. The COSMOS C700M keeps Raising the Bar(s) on custom PC’s by inspiring builders to escape from the “standard” layout.
