Excellent case. I was unable to make this silent I think because of the small air volume and SFF requirement, but if a slight humming doesn't bother you then this case is super easy to build in and look excellent. (I'm just a bit too autistic)

Well designed case. Good quality parts. Looks good. Small footprint. A+

**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. *AIO in pictures is kraken 240 not 280 as I wanted to ensure the cooler was not failing after checking temps.

ALMOST a perfect case!!!! The build quality is excellent. The airflow is fantastic. What is it missing? it should be much taller, to fit a longer GPU. Which means fitting a 5090. But then it also needs to be a bit wider to fit a 5090. So with those two fixes? that would make the perfect case. And since its taller, you could probably fit a 360mm radiator in the front since its taller. Which would be a huge win. Its ALMOST PERFECT. Its already assembled you just throw parts in and you are good to go. No issues with the pci-e gen5 cable! Legit works with my 9070xt no issues!!!! Its a sick case. VERY QUIET. So far been an absolute breeze, and yeah that's the joke.

One of the top itx makes out there glad I bought mine fast. Nzxt should note that they defentntly Could trim down the lower portion of the center where the psu sits the side wall could be trim down (it has twon lil bimps get rid of that,and you could fit a full atx psu. Not to mention a 360mm raid as well top portion could make room would love to see an upgrade version. Send me one lol. Great job NZXT

They made an amazing case. The format is perfect. I don’t really change my displays often but I do change my keyboard, mouse, headset, whatever way more. I do wish they sold a replacement for the glass panel that was just another mesh panel for air coolers. Very good experience overall.

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.
