The huge fan also gives the H100 a strong start in terms of cooling, which is assisted somewhat by the use of mesh to assist the flow of air. The mesh also reduces the overall weight when compared to a solid panel which, when coupled with a built-in carrying handle, makes the H100 nicely portable.
Although it's a mini-ITX case, the MasterCase H100 is able to accommodate a full sized ATX power supply. Between that and the big beast of a fan sitting in the front of the casing, this is a case designed for compact but potentially powerful systems.
The MSRP for the H100 is £54.99 inc VAT.
