Beautiful, Airy, and Easy to Build In
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.

NZXT H9 (UPDATE)
I love this case. The H9 is how best to put it, an inspired design from one of the most popular PC cases on the market the Lian Li O11. All I can say is if you come for the king you best not miss and NZXT hit their mark. The case is high quality, spacious to work in, versatile and elegant. I find the aesthetics of the case to be vastly superior to the 011, the case allows for nearly every part to be easily removed toollessly to make things easy to work on and offers tons of preplaced cable guides to make cable management as easy as possible. This brings me to some of the things I don’t like, I wish the USB were front facing instead of top mounted like on the O11 EVO, Hyte Y60/70 or NZXT’s own H6. I would have liked some rubber grommets covering the cable management holes to make the cables that run to the board look even cleaner. Lastly I would have liked some Velcro straps at the bottom of the case as well for managing things like a multi connection SATA cable from my PSU as well my fan cables/controller. Overall I highly recommend this case or cases like it for first time builders and experienced builders alike. The case offers so many great features and tons of mounts for fans for adequate cooling. It also takes NZXT’s minimalist aesthetic and creates something super elegant that can be a showcase for your build while not sacrificing things like airflow and function. It’s got some quirks but I am just happy to see NZXT whom I consider to be on of the best quality case manufacturers finally making good cases after years of just sticking with the H510. UPDATE: Given some of the let’s say less than savory tactics NZXT has been found to be doing with things like their predatory PC leasing program it might be best to start looking elsewhere in the future and customers should know about this. Won’t change the rating because the product itself is good even if the company that makes it has decided to go down a less consumer friendly avenue.

Case Quality is Amazing
This case while on the pricey end, is one of the best cases I’ve used, it’s sleek, modern, and spacious. While I wouldn’t recommend this case to a person who wants to build something small and more performance based, I would definitely recommend this case to someone who wants to build something aesthetically pleasing that stands out. The potential for this case is amazing and it’s paired with how visually appealing it is, not to mention the room for cable management due to the case’s dual chamber design. This would allow you to just throw the idea of cable management out the window if you don’t care for it. The case isn’t loud considering that it’s surrounded by 3 glass panels, the airflow is as great as you’d expect and it performs great in both the cooling spec and the lighting spec when it comes to aesthetics. The case itself isn’t that heavy, when you first get the package it may seem heavy but that’s mainly due to the glass panels, once removed though the case is basically as light as a feather, this may vary depending on the person, but it isn’t a heavy case regardless for its size. The case is relatively easy to use as well, for first time builders or people who are new to pc building it may be a bit difficult because they’re new to the idea of cable management and such, but to the relatively experienced or knowledgeable builder it’ll be a breeze. Once again, this case is such a perfect product when it comes to aesthetic appearance and lighting inside of the case, it isn’t too much but it just works in the right way, if you have the money I would definitely recommend this case especially right now considering the mark down compared to the previous price which was $200! Seriously though this is hands down the best case I have ever worked with, I couldn’t recommend this case enough due to its current price and all the extra things you get for the price, but only buy it if you’re willing to pay a bit more for a case, there are other cases out there that are cheaper and while they lack some of the things that the H9 does, they’re still great cases.

My dream case ❤️
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.

Fans! Rgb! All the room!
Outstanding case! Pros: comes with all the fans installed, plus the rgb controller installed. Lots of room for all of your pc build needs, and let's you show off the goods! If you haven't seen one in person, it is very large. Has all the room for activities! The backplane has a great area for managing cables neatly allowing for a neat and clean looking build. Cons: it's big. That may not be within your needs. It will need to be set on a hard surface or on a pc stand to allow the air to flow from the bottom fans.

This thing is HUGE! No wonder it has great airflow.
I bought the H6 Flow and this H9 Flow RGB+. The video reviews I've seen of this case, didn't really give it a sense of scale. This is a monster of a case, the largest I've ever had. Mine included all SEVEN ARGB fans. The included fan controller is only good for those fans, which is enough. And get this: They are surprising quiet, unlike the fans in the 6 model, which are running full speed all the time. For me, this is the ultimate in cooling. Combine this with a quality AIO or heatsink fan, and you won't have to worry about your components overheating. The price you have to pay is space to place this thing, and the WEIGHT. This feels like 25 lbs empty. Pros Fan controller included - but only good for controlling the NZXT fans. Fans are surprisingly quiet Quality, heavy duty construction Outstanding interior air flow dynamics CONS May be too large for some people Heavy AF Fan controller is proprietary to NZXT. If you have different brand fans, you will have to get another controller

mostly good, but has an obvious wart
Plenty of space and excellent cable channels makes it a joy to do a PC build with this case. Case fans can be strategically mounted anywhere other than the panel doors to maximize air flow including case bottom. I am however deducting a star for the brain cramp decision to locate front panel connectors and power button at the bottom of the case. What were they trying to do, save a few cents on FP wiring length? It makes no sense. It is a major PITA to deal with these limitations. Unless you want to crouch down every time the connectors would require extension cables. The power button would require some sort of stick (I use a ruler) to reach it. Overall a good product, but NZXT did not think the front panel issues through.

Great case, easy to work with and looks nice
The NZXT H9 Flow (2023) is a great case that rivals other high-end PC cases in my opinion. My experience building with NZXT cases has been nice, especially this case. They all feel high quality. There is enough space for cable management, and it is easy to work with. The view of the PC after it is done looks great with the glass side and front. There is space for 10x total fans: 3x fans at the top, 3x fans on the side, and 3x fans on the bottom, plus space for a single fan at the back. There are holes on the top, bottom, back, and whole side of this case, with dust filters included. My PC stays cool. For storage, there is a bracket that swings out and holds 5x 2.5" drives on the inside. There is a hard drive bracket that holds 2x 3.5" drives and 1x 2.5" drive. I think it would be nice if there were space to add one or two more 3.5" drives, though it is okay and should work for most people. Although with the AIO setup and this case, the PC is now heavy and not very portable. The top front I/O has: Power Button 2x USB 3.2 Gen 1 Type-A 1x USB 3.2 Gen 2x2 Type-C (20 Gbps) 1x Headset audio jack Overall, I really like this H9 Flow PC case, the way it looks and to build with it.
