NZXT FLOW H2
Came in just like I ordered.
Now if they could just make a NZXT ITX motherboard that would work in it :)
I also need a 280MM black radiator back in Stock.

My new favorite Case built
Love at 1st sight, I know it sound cheesy, but it's the truth. I couldn't wait to get my hand on this and upgrade my computer. I used to have the H1, and it was one of my favorite builds—until the H2 came out. Now, this is my new favorite.
At first glance, the case is beautiful, slick, and modern with an update look from the H1. I had to wait to start the built since I order a new GPU and PSU, but as soon it was delivered, I started the built. It had plenty of room in spots and a bit snug in other parts. I still had a blast on the built and using the Kraken Plus 280 on my new built, only complemented it.
Everything was easy to fallow on the built, the only thing I struggle was on the two spots for the SSD 2.5 slot. They were very closed to each other, so when it came to plugging them with the power and Sata connection it was very challenging. I had to bend the power cable so they can be closer to each other in order to plug them in. Maybe if there space out a bit more, they were very snug to the bottom of the case.
I enjoy the extra slots for zip tied for cable management, but the Velcro were hard to grab at times, maybe if they had a ring on one side you can loop it and pull to Velcro it together instead of overlapping, other than that I love the case especially split on glass and mesh.
It's wonderful to know that the case is design to grow with the user in time, meaning I can upgrade it knowing that theirs more room to work with. Way to go NZXT Team.

Frequently Asked Questions

Can I install a full-sized graphics card?

Yes. The NZXT H2 Flow supports graphics cards up to 331 mm in length and 65 mm thick (3-slot), including cards such as the NVIDIA GeForce RTX 5090 Founders Edition (304 mm) and AMD Radeon RX 9070 XT models (288–330 mm).

GPU clearance is measured using a standard graphics card profile. When installing front-mounted AIO cooling with a larger tube cover—such as the NZXT Kraken Elite—available GPU width clearance may be reduced.

Some modern GPUs feature wider coolers, extended shrouds, or repositioned power connectors that require additional clearance. Radiator thickness, tube cover size, and breakout cable placement can also affect fitment. As a result, some wider GPUs may contact the radiator, tubing, or cables even if their listed length is under 331 mm. Please check your GPU’s width dimensions and plan accordingly. Alternatively, the radiator can be installed at the front of the case with the fans positioned behind it in a pull configuration, which may provide additional clearance around the radiator fittings and tubing.

Does the H2 Flow support air cooling for the CPU?

Although the H2 Flow is designed primarily for liquid coolers with LCD screens—supporting front-mounted radiators up to 280 mm—a low-profile air cooler can also be used. Please note the 75 mm CPU cooler height clearance, and allow at least 10 mm of space between the top of the cooler and the glass panel.
