    • 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. ... show more

    • My dream case ❤️
Size: Non RGB Fans Style: H9 Flow Color: Black
Review Image by Harte Harte
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. ... show more

    • Beautiful, Airy, and Easy to Build In
Size: Non RGB Fans Style: H9 Flow Color: Black
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. ... show more

    • 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. ... show more

    • Fun and exciting case!
Great case, pretty to look at and spacious enough for the latest hardwares including the newest 5090 cards. Airflow feels amazing, comes with 4 fans which is enough to make my pc to regulate temperature, with obvious additional parts like a cpu water cooler and radiator. My only issue which isn’t a huge problem is the center piece for cable management makes a right squeeze for my GPU, but that can easily be fixed by removing that one piece by unscrewing 2 screws. F panel is also really nice and easy to install, rather than the old system with multiple tiny plugs for power, reset and LED, it’s all one simple plug, saves a bunch of time and makes cable management so much easier! 9.5/10 ... show more
