The media could not be loaded. The Dual chambers of this case make building in it that much more convenient cause of how spacious it is inside. It can properly fit a few different motherboard sizes, including Mini-ITX, Micro-ATX, and ATX with some reporting E-ATX as well after removal of the cable management tray. A couple standoff screws I had to remove took some fiddling with a wrench but that's to be expected. The cable management is on another level, there are useful velcro straps in the rear chamber that go up and around the top of the case, with all of the case's front I/O Input cables and stock fans' cables routed through them already. The build quality of the case itself is awesome to behold, it reminds me of a fish-tank, but it's for your computer! It definitely has some heftiness to it, the tempered glass panels have a black border around 2/3rds of the panel, but it's pretty easy to get your fingerprints on them at one point before putting it all together, so have a lint-free micro-fiber cloth at the ready and maybe some Isopropyl alcohol. When it all comes together, an Intel i9-12900k sits around 35C at idle during the spring time thanks to the NZXT Kraken 360mm AIO liquid CPU cooler. The GIGABYTE Aorus GeForce RTX 5070 Master sits near 32C at idle with help from three 120mm bottom intake fans. I also ran a few recently released or demanding games at the highest settings possible at 1440p at a max of 165FPS to monitor how temps were: Marvel Rivals - Temps were under 58C and CPU temps hovered around 45 capping at 49C in the Practice Range area at high GPU/CPU loads. The Elder Scrolls IV Oblivion Remastered - GPU at 98% load and temps didn't exceed 58C while taking down the yellow team in the arena and traversing Cyrodiil. CPU temps were consistently under 55C as well. Throne and Liberty - CPU Temps hit 67C max during shader optimization and GPU was mostly around mid 50s, capping at 58C while running around in shapeshift form. CPU didn't exceed 58C during normal gameplay either. Call of Duty Warzone: CPU max temp was 62C and GPU's was 59C. God of War Ragnarok: GPU and CPU temps didn't go above 60C during multiple Valhalla runs. My one caveat with this case: The side panel can be tough to get properly seated after opening. The two glass panels meet and there's a bit of a gap, which is normal, especially since it comes shipped with a piece of cardboard between the two, but I noticed the gap was slightly bigger than when it shipped, and that the bottom circular shaped rubber notches weren't properly inserted. I think I ran into this issue during my first attempt to re-insert the panel cause I had the case vertical. I then turned it on the perforated mesh side of the case and figured out the method that worked for me to get the panel back in properly. Solution to re-insert glass side panel: I had to basically angle the tempered glass panel towards the bottom to fit the circular notches at the top correctly, then lower the panel to the bottom of those lower notches while pushing the top of the panel inwards so that the topmost spherical notches insert into the corresponding circular cutouts there. (Doing all this while avoiding leaving any fingerprints and smudges on the inside of the panel can be tough!) tldr: Great case to build with, display, and admire! One caveat: the glass side panel is a bit tough to re-insert.

Was not a big fan of NZXT cases as I thought that the build quality fell short of others such as Lian Li and Corsair as well as the Hyte Y70 Touch. This case has changed my opinion for various reasons. The build quality is superb, the aesthetics are flawless except for one thing. That one thing is the lack of rubber grommets for cable management otherwise this would be a perfect case. Cable management at the rear of the case is the best I have ever used with lots of room to spare. I love the single frame RGB fans and the the fan hub this case comes with. I just wish they were reverse blade so that the front of the fans would show (a minor nit I admit). I would without hesitation say that I am very happy with my purchase. Bravo NZXT!

I’ve had this for 7 months now, and I think it’s time I finally write a review. I get compliments on this case ALL. THE. TIME. My setup looks soooo clean now and this case really ties it all together. There’s so much space for airflow and cable management, and the size of the case made it easy to get in and assemble. I’m fine with the fans it came with, and haven’t bothered swapping those out because it stays pretty quiet and stays cool. I love the magnetic mesh top that pops off for easy cleaning in-between deep cleanings, and the mesh tray at the bottom that slides out. I love how many configurations there are for airflow or for your radiator, and I LOVE how the PSU gets hidden in the back alongside the cables. Maybe I’ll update this review with a picture of my cable management, because I’m really happy with that too. I love that the windows are glass panes instead of plastic/acrylic that might scratch easily. Everything about this case just feels high quality.

Great case, fits pretty much everything you'd need. Tempered glass looks great and overall it's a really good-looking tower. Haven't had any issues with air-flow so far, with the Kraken Plus 360 AIO I haven't had my CPU go over 50 degrees yet even while running Premiere Pro alongside a few background applications. The software lets you control the fan speed and noise, and they were dead silent - I did adjust them to a performance setting because I don't mind the noise, but even then it's quieter than what I'm used to.

The NZXT H9 Flow is hands down one of the best cases I’ve ever built in. The dual-chamber design makes cable management incredibly easy and clean. The airflow is excellent, especially with the perforated top panel — my temps stay low even under load. The tempered glass front and side panels show off your build beautifully, and there’s tons of room for fans or a 360mm radiator. It’s well thought out, sturdy, and looks amazing on my desk. If you're building a high-performance rig, this case is 100% worth it.

GPU runs cooler than my CPU, I have a RTX 2070 and I switched to this case from a "be quiet! Pure Base 500DX" as my GPU was running hot and I could hear the fans on it spin up through the case. GPU temps stay under 70c now. Case also has loads of room for cable management and its super easy to install anything. It looks great and if you put the fans in silent mode in NZXT CAM software the only thing I can hear is the one and only mechanical HDD I have in the system. Super functional and and well thought out. Screw quality is fine I just wish the labeling was better and the print on the case manual wasn't so small. If you can afford it by the case.
