    • Fantastic upgrade over H1
Upgraded from an H1 to this. The H1 had fresh paste and the pump and fan were indeed working, and my 5900x IDLED at 70 c. I've transplanted that whole system into the H2 (along with an arctic 280mm AIO) and the temps now idle at about 36ish. Heads up if you have the same idea to fit the same arctic AIO, it is quite a bit of a trick to fit the tubes in. They are just a bit too long for a simple route. ... show more

    • It's a really good case.
Review Image by CDubbsW0rld CDubbsW0rld
This case is what I was looking for. It's not too different from the SSUPD cause but, IMO the build quality is better. I appreciate I do not need right angle adapters for the GPU (or to buy taller feet), PCIE Gen 5 riser and lastly, the split glass looks dope without compromising on temps. Downsides would includ only being able to use sfx/sfxl PSU, only itx boards but for me, it's a non issue as space is a premium. ... show more

**Quick notes / TLDR** - SFX psu required, good looking case, great accessibility. Arctic 240/280mm radiators will fit with fans mounted on the inside and rad mounted outside of removable bracket. Your average dp cable and hdmi cables work fine, don’t need angled. Price vs performance is good but debatable. 8/10. First off I want to say I am a fan of nzxt cases. I ordered this case with a bias that it would be of good all around quality as I’ve owned and appreciated almost every variant of their flow series. That being said here is my pros and cons. Cons: - too much space in all the wrong places. I moved my itx build over from a TT TR100, and while I appreciate the smaller footprint, the open spaces of this case near the psu(bottom of the case) and near the top of the case(between the motherboard and case fan housing) seem counterintuitive. There is little to no cables or cable management that need to be done in these areas and leads to unnecessary cable run lengths and wasted space when looking at it from a sff case perspective. - Cpu thermals are subpar* When comparing this to cheaper mitx cases such as the TT TR100 and Tower 250 I’ve actually seen a RISE in temperatures on the cpu side of cooling. About 5~7c degrees idle and 10~15c under load or gaming, while using the same kraken plus 280 AIO cooler with reapplied thermal grizzly kryonaut across all 3 builds. - Small but notable con; the pcie riser has a bit too much slack and is going to be pressed against the gpu somewhat firmly. Pros: - It looks good, the glass panel is a nice-to-have and is well implemented. The glass meets the mesh panel right above where you would begin to see your psu cabling so the build will look clean with minimal ocd level cable management. - Accessibility, as with most NZXT cases, building in this case was very easy. Every panel is removable and you have access to every cable, plug, and header you need to reach. Nothing on the case needed to be modified, shimmed, or shaved, it just fit. - Gpu temps are on average better vs. cases with no immediate exhaust fans. If you have questions before there are several other reviews, reach out to me on insta. @ohhlayne *AIO in pictures is kraken 240 not 280 as I wanted to ensure the cooler was not failing after checking temps. ... show more

    • Finally scratched my ITX itch
Great ITX case. Very easy to build in but requires planning, like all ITX cases. Really appreciate the small footprint. Made from quality metal and feels sturdy.
