7.2/10verdict: good, not the best

The NZXT H6 Flow is for builders who want a mid-tower with strong cooling and an easy build. It suits gaming and general desktop systems with a graphics card, an air cooler or a top-mounted radiator, and only a few drives. It is less suited to storage-heavy builds or anyone who wants a quiet system at full fan speed.
