Compact micro-ATX case for high-performance builds

The NZXT H3 Flow is a white micro-ATX chassis that fits full-size components in a space-efficient footprint. It targets builders who want powerful hardware without a large tower taking up desk space. Buyers who need E-ATX motherboard support or multiple 3.5-inch drive bays should look elsewhere.

GPU clearance depends on front cooling configuration

Maximum graphics-card length is 377 mm with no front fans, 352 mm with front fans installed, and 317 mm when a front radiator and fans are fitted. Choose your cooling layout first, then verify your card fits the corresponding limit.

Mesh panels and a pre-installed rear fan manage

Ultra-fine steel mesh on the front, top and sides plus a ventilated PSU shroud deliver high airflow while filtering dust. One 120 mm rear exhaust fan is included; the case supports up to seven fans and radiators up to 280 mm front and 240 mm top for scalable cooling.

Questions about this item

How long a graphics card can I install if I also want a front radiator and fans?

With a 280 mm front radiator and its fans fitted, the maximum GPU length is 317 mm, so choose a card at or below that measurement.

What radiator sizes do the front and top mounts support?

The front mount takes a 280 mm radiator and the top mount takes a 240 mm radiator, letting you run liquid cooling in both positions.

What fan sizes fit the front, top, bottom and rear positions?

The front and top accept two 140 mm fans each, the bottom takes two 120 mm fans, and the rear comes with one pre-installed 120 mm fan.
