NZXT H3 Flow Case Review
NZXT is one of the most recognisable brands for PC gamers, with an award-winning range of cases, coolers, power supplies, peripherals and much more. Of course, one of the biggest selling points of NZXT, other than their fantastic performance, is their aesthetics. All NZXT hardware tends to fit together, look great together, and provides you with a striking aesthetic thanks to their clean and stylish brand identity. The brand-new H3 is their latest product that aims to meet those standards. What’s interesting is that it is a micro-ATX case, a very underserved part of the case market these days, as there are so few mATX motherboards hitting the market with the majority of motherboards being made in the more popular mini-ITX and ATX form factors.
NZXT H3 Flow
Despite its size, the H3 Flow promises quite a lot of interior space, allowing for larger liquid coolers, more fans, and, given its 2025, a graphics card that looks the size of a battleship. It borrows some of the airflow-focused design ideas that made last year’s H5 Flow so popular, but being the H3, this is a smaller version, but still offers the space required for modern high-end builds, making it a bit closer to a standard mid-tower in some ways. This makes it well-suited for gaming builds in smaller bedrooms or work-from-home spaces.
