Compact Mini Tower gaming case designed for users who do not want to compromise on cooling when building a high-performance system based on micro-ATX. The design is based on the concept of maximum airflow, implemented through perforated panels with ultra-fine mesh at the front and top, which effectively filter dust. The chassis offers extensive options for cooling organization: up to seven fan mounts and support for liquid cooling radiators up to 280 mm at the front and 240 mm at the top.

One 120 mm fan is pre-installed on the rear panel for hot air exhaust. Despite its compact size, the interior space allows for full-size graphics cards up to 377 mm long (without front fans) and CPU coolers up to 170 mm high. A key feature, oriented towards modern trends, is the support for motherboards with back-connect connectors. This, combined with well-thought-out cable management channels, allows for an exceptionally tidy build appearance. On the top panel of the NZXT H3 Flow case are peripheral connectors, among which stands out a high-speed USB-C 3.2 Gen 2x2 port.
