NZXT H9 Flow RGB Dual-Chamber Mid-Tower Case Overview

The NZXT H9 Flow RGB (2025) is a premium dual-chamber mid-tower ATX case engineered for high-performance PC builds that demand excellent airflow, clean cable management, and stunning visual presentation. With expansive radiator support, panoramic tempered glass, and next-gen back-connect motherboard compatibility, the H9 Flow RGB is built to handle powerful gaming and creator systems with ease.

Dual-Chamber Design for Cleaner Builds

The H9 Flow RGB features a dual-chamber internal layout, separating core components from the PSU and storage drives. This design improves airflow efficiency, reduces heat buildup, and keeps cables hidden for a cleaner, more professional build appearance.

Optimized Airflow Architecture

Designed with airflow as a priority, the case uses perforated steel panels and angled front-right fan placement to guide fresh air directly toward the GPU and CPU. This layout ensures consistent cooling performance even in high-power configurations.

Pre-Installed RGB Cooling Fans

The case comes ready to cool out of the box with:

1× F420 RGB Core single-frame fan installed at the front-right
1× F120Q (CV) 120mm fan installed at the rear

These fans provide balanced airflow and vibrant RGB lighting while maintaining quiet operation.

Extensive Fan & Radiator Support

The NZXT H9 Flow RGB supports up to 10 fans and large liquid-cooling setups:

Front-Right: Up to 420mm radiator
Top: Up to 420mm radiator
Bottom: Up to 360mm radiator
Rear: Up to 120mm radiator

This makes it ideal for custom water-cooling loops or high-end AIO configurations.

Panoramic Tempered Glass Display

With wraparound tempered glass panels, the H9 Flow RGB offers a seamless panoramic view of your components. It’s perfect for showcasing RGB lighting, custom loops, and premium hardware without visible frame interruptions.

Support for Large GPUs & High-End Hardware

The case accommodates:

GPUs up to 459mm (depending on fan/radiator configuration)
CPU coolers up to 165mm
PSUs up to 200mm

This ensures compatibility with the latest flagship graphics cards and cooling solutions.

Back-Connect Motherboard Compatibility

The H9 Flow RGB is back-connect ready, supporting rear-connector motherboards such as ASUS BTF and MSI Project Zero. This allows cables to route behind the motherboard tray for an ultra-clean, cable-free look.

Effortless Cable Management

NZXT includes extra-wide routing channels, built-in Velcro straps, and multiple tie-down points to make cable management simple and efficient, even for complex builds.

Front I/O for Modern Connectivity

Convenient front-panel connectivity includes:

2 × USB 3.2 Type-A
1 × USB 3.2 Gen 2×2 Type-C
1 × Headset audio jack

Perfect for fast data transfer and modern peripherals.
