One of the coolest cases around is the NZXT H1 mini-ITX case. With a classy style, small form factor, and included fitting components, it's a super attractive option for any PC builder. Why are included components important, you might ask? Well, they aren't super useful with most cases, but for mini-ITX, where there are very few options, components that fit perfectly and blend in are a huge bonus.
We're not going to be doing a sample build, as there are no ITX motherboards with PCIe 4.0 currently available, and the B550 series motherboards are coming soon, but there are definitely some great things you could do with this case. Imagine how nice it would look in any modern or minimal setup. And the size! You could probably take this in your backpack from home to work if you liked. As for airflow, this case can have a tempered glass front panel while still allowing for great cooling, with areas for fans to draw air through the sides and expel it out the back. All the high-power components, like the PSU and GPU, are lined up against the sides to get tons of air with their own fans. This is a wonderfully efficient design that, combined with the case' small size, eliminates the need for extra case fans. As for aesthetics, the H1 doesn't seem like a case for an aggressive RGB build, but more of a modern build.
The three extra components that come with the H1 are a PSU, water cooler, and PCIe riser card. The water cooler is an AIO with a single 140mm fan. It will be a huge upgrade over your conventional Wraith Stealth cooler. Unfortunately, there is only one fan, but that kind of makes sense considering how small the case is, and plus the fan is bigger than the usual 120mm. The H1 also comes with an excellent 650 watt, 80+ Gold, fully modular power supply. The most powerful configuration you could put in this case, with thermals considered, probably won't need more than 650 watts. And lastly, the PCIe riser card is very useful for effective space management with your GPU. Although it is a PCIe 3.0 card and imminent motherboards will run with PCIe 4.0, the card is meant for GPUs and the area where PCIe 4.0 is most useful is extremely fast SSDs (Think Optane).
This case is also incredibly easy to build with, especially for a mini-ITX case. There is great design all around, with tool-less SSD installation, easy motherboard installation, and of course the built in components whose cords have already been routed for you. The PSU is, of course, modular, which will help a ton with having a fresh-n-clean build.
And finally, is the H1 a good price value? Well, let's look at the components. A good ITX case is around $80. The EVGA PSU equivalent of this case' PSU, the NOVA650, is $130. And the Cooler Master MLY 140mm AIO is $175, although a 120mm AIO is just $70. Additionally, you're paying for the H1's easy assembly, great design, and modern aesthetic. So overall, a decent deal, considering the H1 is $350. If I was going to build an ITX PC, I would definitely consider using the H1.
