Find your fit.

Two families, one idea: a case that gets out of your way. H-series runs Mini-ITX to dual-chamber ATX. S-series starts with the S5 RGB — side-intake airflow, light built in. Clean by default, RGB by choice.

Why NZXT Cases

Designed around the builder.

Performance

Tempered glass, mesh intakes, and large AIO support tuned to every form factor — from 20.7 L SFF to 76.6 L dual-chamber.

Usability

Tool-less panels with hinged openings. Pre-routed cable channels. Factory-wired RGB. Your first build — or your fifteenth — still feels good.

Expression

Glass panels showcase what you built. A neutral visual language keeps your components the hero — black or white, one aesthetic.

Quality

Durable steel, flush-mounted tempered glass, and a 2-year warranty. Built to hold the same parts through multiple upgrade cycles.

Reviews · Press · Video

Built, reviewed, loved.

From press and tech media

Even the best SFF cases I've tested can't match the temps of the H3 Flow.

The NZXT H6 RGB+ is a feature-packed, thermal-performance powerhouse of an ATX case.

It's really refreshing to see a $49 chassis that has great airflow, great construction quality, great build quality.
