The NZXT H3 Flow 2025 in White is a sleek and modern Midi Tower PC case designed to support Micro ATX and Mini-ITX motherboards. Built from a combination of mesh, SGCC steel and tempered glass, this white enclosure offers a clean aesthetic while maintaining strong structural integrity. With dimensions of 400 mm in height, 225 mm in width and 389 mm in depth, it strikes a practical balance between compact sizing and internal spaciousness. A side window and tempered glass panel provide a clear view of the internal components, making it a solid choice for those who value both form and function.
Airflow and Cooling Capabilities
The H3 Flow 2025 is built with airflow as a priority. The mesh front panel allows for efficient intake, and the case supports up to two 120 or 140 mm fans at the front as well as two fans on the top and two at the bottom. A single 120 mm fan comes pre-installed at the rear. The front can accommodate a 280 mm radiator while the top supports up to a 240 mm radiator, giving users meaningful liquid cooling options. The maximum CPU cooler height of 170 mm provides room for most tower coolers.
Connectivity and Storage
On the front panel, the H3 Flow 2025 includes a USB 3.2 Gen 1 Type-A port, a USB 3.2 Gen 2 Type-C port and a combined headphone and microphone jack. Storage options include three 2.5 inch bays and one 3.5 inch bay, covering a range of drive configurations. Four expansion slots and support for graphics cards up to 377 mm in length round out the internal flexibility.
