Price and rating as shown on Amazon when we collected them. Both change.
The NZXT H5 Flow is the third case in this guide: a compact ATX mid-tower in black, listed at £49.99 and rated 4.6 out of 5 from 1,190 ratings. It is the tidy counter-example to the pattern running through the rest of the list. The spec table says 'Number of Fans: 2', and that is what arrives — the item highlight says '2 included 120mm fans'. The larger figure, up to 10 x 120mm or 6 x 140mm, sits in the bullets and describes what the chassis will hold, not what comes in the box.
Other numbers on the same page are less tidy. The spec block lists 2 x USB 2.0 ports, 2 x USB 3.0 ports and a 'Total USB Ports' of 2 — the first two add up to four, not two. It gives a 'Power Supply Maximum Output' of 500 Watts for a case, with no power supply described as included. And it lists the case as 47D x 43W x 23H centimetres, which makes the width figure larger than the height figure. Everything below comes from the retailer's listing, not from our own testing.
How those 1,190 ratings break down
