Customers are saying

Customers love the H9 Flow ATX Mid-Tower PC Case, especially its spacious interior, excellent airflow, and superior cable management. The case's design and ease of assembly are also highly praised, along with its overall appearance and sufficient size for PC components. However, some customers noted that the included fans are not RGB and the case can become quite heavy when fully built.

    Was told this had RGB lights included but it didn't so I'm sure I overpaid but after the install of my choice of fans and ram I have all the light I need. Works well looks clean and love the white set up.

    Probably one of the best case I use for a pc build, a lot of options for fans and the power supply is mounted at the top instead of the bottom so u can put you’re pc on the floor if u wanted to.

    This is my second NZXT case. This one for an RTX 4090. I thought the case design could not get any better, but I was wrong. The design and functionality of this case is first-class.

    Excellent Airflow and incredibly easy to build in. Just what I was expecting for such a large case. I had to vertically mount my 4090 and there aren't a ton of great options, so was happy to return to a NZXT case.

    Absolutely love the build! Ended up building a full build with Corsair fans instead of the stock nzxt fans! However both fans are amazing! Love how the build ended up looking in the end!

    Wonderful case! Lots of space, and looks great. Only reason I didn’t give it 5 stars is because I ASSUMED the pre-installed fans would have some sort of RGB…they did not. Still a great case and I’m extremely happy with it! If I could I would give it 4.5 stars but I don’t believe I can. I ended up buying 3 replacement fans but not a big deal.
