NZXT H3 Flow MATX Mid Tower Cabinet ( White )

The NZXT H3 Flow (model CC-H31FW-01) is a Micro-ATX mid-tower PC case designed for builders who want efficient airflow in a compact, clean-looking enclosure. Constructed from SGCC steel with a clear tempered glass side panel, the white variant offers a modern aesthetic while maintaining structural rigidity. At its core, the H3 Flow is engineered around airflow. Ultra-fine steel mesh panels cover the front and top of the chassis, allowing ambient air to move freely into the case, while a ventilated PSU shroud contributes to consistent thermal management across the entire build. The case ships with one pre-installed F120Q (CV) 120mm fan at the rear, operating at up to 1,350 ±150 RPM, delivering 60.2 CFM of airflow at 1.05 mmH2O static pressure and a noise level of 24.1 dBA. The 3-pin DC connector makes it compatible with standard motherboard fan headers. Cooling expandability is a highlight. The front panel supports radiators up to 280mm and can accommodate two 120mm or two 140mm fans. The top supports up to a 240mm radiator with two 120mm or 140mm fan slots, and the bottom can house two additional 120mm fans, bringing the total potential fan count to seven. This range of cooling options makes the H3 Flow suitable for both air-cooled and liquid-cooled configurations. For GPU builders, the case supports graphics cards up to 377mm in length when no front fans are installed, up to 352mm with front fans, and up to 317mm when a front radiator and fans are both mounted. CPU cooler height clearance is 170mm, accommodating tall tower coolers. The PSU bay supports units up to 185mm in length. Front I/O includes one USB 3.2 Gen 1 Type-A port and one USB 3.2 Gen 2x2 Type-C port. Storage options cover one 3.5-inch and three 2.5-inch drive bays (one dedicated plus two combo). Four standard PCIe expansion slots are available, with no vertical GPU slot. The H3 Flow supports Micro-ATX and Mini-ITX motherboards. Notably, it is compatible with rear-connector motherboards such as ASUS BTF and MSI Project Zero (Micro-ATX size), enabling a cleaner front-facing aesthetic with fewer visible cables. Integrated cable channels and multiple tie-down points, plus up to 31.5mm of cable routing space behind the motherboard tray, simplify cable management. Tool-free removal of the top, front, and side panels makes routine maintenance and component upgrades more accessible. The case measures 400mm (H) × 225mm (W) × 389mm (D) with feet attached, has a volume of 35.0 litres, and weighs 4.8 kg.
