PC Midi Tower case NZXT H9 Flow RGB+ — White, supports ATX/EATX/Micro-ITX, tempered glass, 3x140mm front + 1x120mm rear fans

The NZXT H9 Flow RGB+ is a white mid-tower PC case designed for high-performance systems and showpiece builds. It features a spacious dual-chamber layout with wraparound tempered glass panels for a continuous view of internal components, extensive cooling support including mesh panels and angled front-right fans, and compatibility with a wide range of motherboard sizes.

Advantages

The dual-chamber design separates heat-generating components from the power supply and drives for improved thermal performance and cleaner cable routing. Ultra-fine mesh panels and angled front-right fans optimize airflow while filtering dust. The case supports large radiators and long graphics cards, and includes RGB-ready fans and a control hub to simplify lighting and fan management.

Suitable for

• High-performance gaming or workstation builds
• Showcase systems with tempered glass side panels
• Custom liquid cooling with large radiators (up to 420 mm)
• Builds requiring extensive cable management and clean presentation

How to use

Install the motherboard compatible with EATX/ATX/Micro-ATX/Mini-ITX standards and mount the power supply and drives in their respective chambers to keep power and storage segregated from the main component area. Configure fan and radiator placement according to your cooling plan—top and front-right panels accept large radiators up to 420 mm, and the case can accommodate up to nine 140 mm fans plus a rear 120 mm fan. Connect included RGB fans and the NZXT Control Hub to the motherboard or power source following manufacturer instructions for lighting and fan control. Use the extra-wide cable channels, built-in Velcro straps, and tie-down points to route and secure cables for a tidy build.

Recommendations

For optimal airflow, position intake fans behind the mesh panels and orient the angled front-right fans as recommended by NZXT. When installing large radiators or long GPUs, verify clearance against motherboard components and cable routing paths. Use the dual-chamber layout to separate hot components and minimize airflow obstruction, and periodically clean mesh panels to maintain dust filtration and cooling efficiency.
