6.4/10verdict: good, not the best

The Jonsbo D31 MESH Black suits builders putting an ITX, DTX or M-ATX board in a case that takes a large graphics card. It also suits anyone planning a 240, 280 or 360 mm radiator. Buyers must supply their own fans, so it works best for people happy to choose and fit them.

NZXT H6 Flow

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.
