This case as completely overhauled my build in all the best ways. Better esthetics, quieter fans, lower temps, the dual tempered glass allows me to appreciate all of the rgb in my system. The high airflow designed has chopped 10 degrees Celsius off of my cpu and gpu temps. It comes with all of the hardware you could ever need for installing components. Theres enough room to run standard profile rgb ram and still run a top mounted aio. Lots of built in cable management options. Im a huge fan of the psu storage design along with all of the space for my ssd's and hard drives. 11/10 love this case

Coming from an H510, I loved all the extra space in the back for cable management, the port holes and tie downs made hiding cables from the front seamless. The option of a side(front) mount 360mm or top mount made me feel safe about cooling. The last case was a nightmare for that. Also, if you wanted to just run a bunch of 120/140mm fans, theres enough airflow to cool a ryzen 9 and a blower style gpu. Be prepared to break you back though, it is one heavy case.

Everything is really well positioned and accessible. It looks amazing in black. My graphics card RGB complements the fan RGB. Getting back in to install upgrades is super easy. I liked it so much I have 2.

This case is awesome! Bigger than I originally thought but it has more than enough space for any graphics card or motherboard. Standoffs for the motherboard are clearly labeled which is a great feature for any first timer new to building their own pc. The cable management offered is great and there’s plenty of room for hard drives.

OMG LOVEEE ITTT! CASE IS CLEAN AND A TON OF SPACE. tho is extremely heavy besides that beautiful!

As described. Lots of space. Glass is beautiful to see into. Vent space for days.

This case has incredible versatility for fans and AIOs. It was very easy to build in. The H9 Flow also has great airflow, and also has a great fishtank design. Though it's a big case, I do like it.

Excellent case, excellent view, really roomy and really easy for the cable management.

My second time purchasing NZXT case and I love this case so much dual chamber is the way to easy wire management and this is my first build so much flow in this case deserves 10 stars

The case is large but mighty good! Cooling power is the best part! If you can stand the large size thus case is hard to beat. Best decision in awhile!

Bought both the big and small version of this case. You can fit an extended mobo but it sticks out a little bit past the spot for the card. Lots of room for cable management

Plenty of space for what I needed to build a PC with BestBuy!

I love it is so big to decorate inside and have the soace in the back for the cables

Excellent case overall. The NZXT H9 Flow RGB has a ton of space to work in, which made building and cable management super easy. The dual-chamber layout keeps everything clean and organized, and airflow is outstanding—temps have been noticeably better, even under heavier loads. The included RGB fans look great without being over the top, and the case feels sturdy and well-built. If you’re planning a high-end or airflow-focused build and want something that’s both functional and clean-looking, this case is a great choice.

Had to buy this case after I discovered my 5070 was too big for my old case (whoops bad research on my part), got the case same day from best buy, super easy. It is on the larger size; HOWEVER, it is spectacular. The latge size gives you great cable management and airflow. I would suggest buying the NZXT triple fans (the same one the comes with the case) so you have better airflow, mine works great with just one exhaust fan on the bottom and the intake on the front that it came with. The power button and ports are on the bottom, but it is a show case so you would ideally have it on your desk/table.

Super nice case with alot of space & airflow. Came with cable management ties already installed.

Very spacious and has very good air flow. Love that is was easy to take the sides off. Made it very easy to install everything.

I had an older nzxt custom built system. I needed to upgraded from a 2070 to a 5090 in order to drive a large super high resolution monitor. I searched numerous cases, while plenty would work, i found this to be the best case and form factor to support my needs. Plenty of room for airflow and cooling.

Built a new pc for the new year and this case is nice and spacious with ample cable management devices.

Great case the design is just awesome the battery is in the back away from the build it just makes nzxt look good with the case design
