NZXT H1 CASE REVIEW: Great temps in a small form factor

NZXT H1 Case Review

The NZXT H1 was announced last year as a small but powerful compact build with an elegant flow but we saw a sample of it way back in Computex 2019 as an added showcase by NZXT.

Key features:

  • Included components (140mm AIO, PCIe riser card, & PSU) cost around $250
  • The 13.6-liter size supports almost all GPUs on the market.
  • Footprint uses just 350 cm (squared) of desk space.
  • Integrated PSU, PCIe riser card, AIO liquid-cooler.
  • Features tool-less SSD tray, easy-to-install riser card, and pre-routed cables.

The new ultra-compact H1 ITX case comes with a 650W 80+ Gold SFX modular power supply and a built-in NZXT 140mm AIO liquid cooling setup giving you more than what you need to build your next ITX PC.

The case is best for those who want a minimalist pc set up as it has a monolith-like exterior with mesh on the sides. Measuring 187x187mm, it takes up a very small space on the desk. It very much resembles the Xbox Series X.

The top panel also has minimal ports consisting of an LED-lit power button, a single USB-C Gen 3.2, USB-A and an audio I/O jack.

To get inside the NZXT H1 case, you’d have to remove the front tempered glass panel and the rear panel. This will allow you to unlock the single U-shaped white mesh side panels.

Despite being a mini-ITX chassis supporting only the smaller motherboards, the NZXT H1 gives enough space to be able to move around the case when setting up the components.

Underneath the motherboard, the PCIe GPU riser is located wrapped and placed around the opposite side to fit a GPUs with dimension – 305mm x 128mm; 265mm x 145mm and a thickness of up to 2.5 slots.

The AIO that is included in the NZXT H1 reminds us of the Kraken M22 with the pump mounted at the center of the radiator.

Upon installation of the motherboard, swivel fittings are fitted to be able to easily move the tubes around connecting the radiator and fan into the mounting position.

Despite having only one 140mm fan that is mounted to the radiator and a secondary RPM is the cooler’s pump RPM., we got really good temps using the following build

Build Specs

Motherboard: Gigabyte Z490I AORUS ULTRA
RAM: 8×2 3200Mhz HyperX Fury RGB

With the motherboard placed and cooler mounted, closing the NZXT H1 shows how compact the complete build is. The layout and preparation of the cabling, cooler, and drives show how well-thought-of the case was designed. 

The bottom part of the H1 shows the motherboard I/O panels, GPU ports and power supply connection. Since the NZXT H1 is designed to be vertically placed, NZXT made cutaways to provide cabling direct out of the bottom.

Closing Thoughts

NZXT gives a lot of value to the H1 chassis thanks to the inclusion of the 650w PSU and 140mm AIO. Everything has been wonderfully cable wrapped and the cooler has been pre-installed giving builders less to worry about. Priced at ₱20,000 at the time of writing, we can say that at this price point, it is quite decent as the price for putting together everything included would come to about the same price or possibly even higher. 

For those that are worried about the H1 case safety issue, they’ve released a statement regarding this and have already begun updating the PCIe riser cable assemblies. Hopefully, there wouldn’t be any hazards but this is our first mini-ITX review and we are glad that it was with the NZXT H1.
