The NZXT H3 Flow redefines compact computing, offering a powerful blend of high-performance capability and space-saving design. This Micro-ATX chassis is built for builders who refuse to compromise on cooling or aesthetics, ensuring that powerful components remain cool without dominating your workspace. Designed with a focus on optimized airflow, the H3 Flow incorporates ultra-fine mesh panels across the front, top, and sides. This design choice maximizes cooling efficiency while effectively filtering out dust. Furthermore, the ventilated PSU shroud optimizes the intake of air from bottom-mounted fans, ensuring consistent, reliable cooling throughout the entire system. For builders needing maximum flexibility, the H3 Flow supports extensive cooling setups. It can accommodate up to a 280 mm radiator at the front and a 240 mm radiator at the top. The case supports a total of seven fans, allowing for versatile cooling configurations using 140 mm fans (two front, two top) and 120 mm fans (two bottom, one rear). Beyond cooling, the H3 Flow is built for modern, clean builds. It features integrated cable channels and tie-down points, simplifying cable routing for a professional, organized look. It also supports rear-connect motherboards like ASUS BTF and MSI Project Zero, enabling a sleek, cable-free appearance. The case is equipped with a pre-installed F120Q fan at the rear for immediate, efficient exhaust airflow right out of the box. The H3 Flow is ideal for the dedicated PC gamer or enthusiast who requires a high-airflow, compact footprint. It supports full-sized graphics cards up to 377 mm (when no front fans are installed) and provides ample room for large components, all within a space-efficient micro-ATX form factor. With its robust design and focus on performance, the NZXT H3 Flow ensures your powerful PC stays cool, quiet, and reliable for years of use.
