Build To Spec

The MasterCase H100 is a conveniently sized mini-ITX case that can be configured as a portable gaming rig, a tiny living room PC, and a desktop space-saver.  From its industrial construction to its entirely mesh front panel, the H100 fits neatly in the series as a travel-sized alternative.

Compact Mini-ITX

A highly compact layout efficiently uses space to keep dimensions minimized.

Fine Mesh Ventilation

The entire front panel and part of the top panel features Cooler Master’s signature Fine Mesh, proven to filter out dust, provide unrestricted ventilation, and makes the cleaning and maintenance process more efficient.

200mm RGB Fan

Even with compact dimensions, the MasterCase H100 features the H-Series’ iconic 200mm RGB fan.

ATX Power Supply

Full-sized ATX power supplies are supported to improve hardware compatibility and ensure efficient power to the system.

Built-In Handle

A handle is built into the top panel for added portability and on-the-go gaming.

RGB Lighting Control

One RGB controller is included in the accessory pack. Lighting can also be controlled through the reset button if the motherboard does not support RGB control.
