NZXT H9 Flow RGB+ is a spacious ATX mid-tower case for powerful gaming and workstation builds, combining maximum airflow, panoramic tempered glass, and RGB included in the box. Thanks to a dual-chamber design, perforated panels, and support for large radiators, it keeps temperatures low while delivering a clean, premium look.
Airy design for low temperatures
Perforated panels and optimized airflow help maintain stable temperatures even under heavy load. The case supports extensive fan setups and is ideal for high-performance GPUs and liquid cooling.
Panoramic tempered glass and premium look
Frameless tempered glass offers a clear view of your components and RGB effects. A perfect choice for a showcase build where you want the graphics card, cooler, and neatly routed cabling to stand out.
Dual-chamber layout and easy cable management
A separate compartment for the PSU and drives improves airflow in the main chamber and simplifies cable organization. Wide grommets, channels, and mounting points make for a clean build.
H9 Flow RGB+ is designed for builders who want top-tier cooling without compromising aesthetics. The dual-chamber layout separates the main components from the power supply and storage, improves airflow, and significantly simplifies cable routing. The frameless tempered-glass panel lets every detail of your build shine.
Airy steel panels and a well-thought-out fan layout help maintain stable temperatures even in demanding configurations. The case is ready for extensive fan and liquid-cooling setups and also supports modern “back-connect” motherboards (e.g., ASUS BTF, MSI Project Zero) for the cleanest interior with no visible cables.
