NZXT H9 Flow RGB+ is a spacious Mid-Tower ATX case for powerful gaming and workstation builds, combining top-tier airflow, a dual-chamber layout, and panoramic tempered glass. Thanks to mesh panels, support for up to 10 fans, room for radiators up to 420 mm, and included RGB fans + NZXT Control Hub, it’s ready for modern configurations with an emphasis on cooling and looks.
Optimized airflow and mesh panels
Perforated/mesh steel panels and angled fans on the front-right side support a fast intake of cool air and stable temperatures even for demanding builds. The mesh also helps reduce dust while maintaining high airflow.
Dual-chamber design for a clean, cool build
The dual-chamber layout separates the PSU and drives from the main components, improving air circulation and making cable management easier. The interior looks cleaner and better highlights lighting and hardware.
RGB included + NZXT Control Hub
Included are 2× F420 RGB Core, 1× F120 RGB Core (CV), and the NZXT Control Hub for convenient fan and RGB control. The case is ready for standout looks and efficient cooling without needing to purchase the basics separately.
H9 Flow RGB+ is built around a dual-chamber design that separates the main components from the power supply and storage. The result is a cleaner-looking build, easier cable routing, and more efficient heat exhaust. Perforated/mesh panels and a thoughtful layout with angled fans on the front-right side help keep temperatures low even under heavy load.
The case is ready for bold RGB builds: the box includes 2× F420 RGB Core (in a single-piece frame), 1× F120 RGB Core (CV) as the rear fan, and the NZXT Control Hub for managing fans and RGB. Support for up to 9× 140 mm fans (top, front/right side, bottom) + 1× 120 mm at the rear provides plenty of options for quiet or maximum-performance cooling.
