NZXT H3 Flow – Micro-ATX PC Case – Optimized Airflow – Includes 1 x 120mm Rear Fan – Supports Full-Sized GPUs – Fits 280mm Front, 240mm Top Radiator – Back-Connect Motherboard – White

beautiful smaller form factor case, it isn't Jonsbo C6 small, but if you want most modern GPU's to fit and good air flow this is it! The case comes with 1 stock fan side panel for wire management and simple IO with USB type C.has designated area for your PSU which is nice. I had my friend paint mine a hyper shift, and I love it. It's great price and doesn't feel cheap!

Excellent case, extremely well made and designed, especially for $60 Went thru 4 cases in the last couple months, 2 were absolute garbage quality. One was the Okinos aqua 3, a fish bowl style case, very nice and well made but a Lil too small and difficult to plug PSU cables into board. And it didn't have intake fans, only exhaust. This H3 FLOW is slightly bigger but much easier to work cables and it also can accommodate rear mounted plugs. Its the perfect M-ATX case. Not overly flashy, but great functionality and a more understated style. Its a grown-ups PC case, ok, if your a child that's grown old and have a ridiculous brightly colored over designed desk chair with a race car theme that cost way more than reasonably worth, you won't want this case. Its for people with taste and have appreciation for quality made and intelligently engineered products. You want a case that reminds people of something that you might find in a Chucky Cheese or a Showbiz Pizza. Just buy it, well made and tasteful. Even if NZXT is a terrible company that tried to horribly defraud thier customers with a corrupt PC rental scam that targeted middle school aged kids and..... it was a big scandal last year in the gamer scene. Im not a gamer, I'm and editor/content creator, so I could care less about your kids being suckered. Its a good case, buy it or go get a gawdy kids gamer case.

This might be my favorite case. It has excellent airflow and for me is the perfect size, it can fit a full 4090 and micro ATX board with room to spare, but is not obnoxiously big or heavy like a full size case. NZXT makes great cases and this was also a dream to build in. Cable management was easy and nice and clean, and the case looks super slick.

As the owner of two great H5 cases, I was excited to get the H3 for a HTPC build. The H3 is good but disappointing. The good: It's sturdy and well-constructed with good fit and finish. Installation of components was easy. The bad: Cable management was minimal, unlike the H5, despite opportunities even with its small size. Some of the pieces felt cheap.

Great case. Bought for our second build has plenty of room for all the additional fans we’re running water to make sure we had good circulation for the micro-ATX. Everything seems to fit and work fine. Only downsides I have noticed was placement for cable management isn’t as good as the larger cases and access to the lower storage area for HDD, Power Supply, and lower fans isn’t great. Other than that it’s a great looking case with easy access to most components.
