Compact Mini Tower gaming case, released on the market in 2025 and designed to create stylish builds with a minimal number of visible cables. Its key feature is the support for motherboards with reverse connector placement, allowing for an exceptionally neat system appearance. Meanwhile, bulky chassis are not required to accommodate powerful components. The compact NZXT H3 Flow case for micro-ATX boards has a well-thought-out internal layout that fits graphics cards up to 377mm in length (without front fans) and CPU coolers up to 170mm in height, without taking up much space on the desk.
To maintain optimal temperatures in the limited volume, a highly efficient ventilation system is implemented. Perforated panels with fine mesh on the front and top provide unobstructed air intake. The chassis offers up to seven fan slots and supports the installation of liquid cooling radiators up to 280mm in the front and 240mm on top. A 120-mm fan is already pre-installed on the rear panel for heat dissipation. The assembly and upgrade process is simplified thanks to tool-free removable side panels and integrated cable management channels. The modern input/output panel on the top edge of the case includes a USB 3.2 gen1 port and an ultra-fast USB-C 3.2 gen2x2.
