NZXT H9 Flow RGB+ Black
The NZXT H9 Flow RGB+ PC case in black provides the foundation for building high-performance systems with a focus on cooling and a clean design. The Midi Tower construction uses a dual-chamber layout, which separates heat-intensive components from the power supply and cabling. The spacious chassis is ready for the installation of demanding components and can even accommodate extra-long graphics cards. The airflow system allows for the installation of large water-cooling radiators.

Frameless glass and dual-chamber design of the NZXT H9 Flow RGB+
The tempered glass panels meet seamlessly at the corner to create a clean, panoramic view of the interior. This solution provides an unrestricted panoramic view of the installed hardware inside the main chamber. The clean lines of the glass complement the overall aesthetics of the build and make the component lighting stand out. The steel construction of the rest of the case ensures the necessary strength and stability for the entire system. A vertical partition divides the interior space into two separate zones, contributing to better organisation and thermal comfort. The main chamber hosts the motherboard with the processor and graphics card, while the second chamber conceals the power supply and storage drives. This layout simplifies cable management and prevents heat from accumulating in one part of the case. The design ensures direct airflow to key components to achieve high cooling efficiency.
High airflow and pre-installed F420 cooling
The manufacturer has designed the panel perforations to increase the supply of fresh air to hot components. The entire top wall and side panel use a fine mesh for effective ventilation, which works in tandem with the installed fans. The system draws in cool air from the bottom and side, while hot air naturally rises and exits the case. This solution maintains low temperatures even under high CPU and GPU load. Included in the package are two F420 RGB Core units, each integrating three 140mm fans into a single frame. These fans provide high static pressure and airflow, and their installation is very easy thanks to the shared frame. An additional 120mm fan is located at the rear for heat exhaust. The user gets a strong cooling foundation right out of the box.
Water radiator support and motherboard compatibility
For liquid cooling enthusiasts, the NZXT H9 Flow RGB+ PC case offers exceptional options for mounting heat exchangers. Both the top and side positions can accommodate radiators up to 420mm long, enabling the installation of powerful AIO coolers or custom loops. The bottom position also supports radiators up to 360mm. This flexibility allows you to cool even the most demanding processors on the market with plenty of headroom. The visual cleanliness of the interior is ensured by full compatibility with motherboards that have rear-facing connectors, such as ASUS BTF and MSI Project Zero. Using a motherboard with rear-facing connectors concentrates all cabling in the secondary chamber, highlighting the build's minimalist look. Of course, support for common form factors from Mini-ITX to E-ATX remains. This broad compatibility allows the installation of any platform to meet the build's requirements.
Space for graphics cards and cable management
Gaming enthusiasts will appreciate the huge space for a graphics accelerator, which can be up to 459mm long. This figure guarantees trouble-free installation of the most powerful cards of today and the near future. Even with a radiator mounted in the side position, there is still plenty of room for long cards. Vertical card mounting is possible with the purchase of the corresponding accessory, which expands the options for hardware presentation. The second chamber contains wide channels and pre-prepared clips for easy routing of all cabling. Integrated hook-and-loop straps keep cable bundles in place and simplify the overall PC building process. Ample depth behind the motherboard provides freedom in organising cables and speeds up the entire assembly. The result is a clean interior that does not obstruct airflow.
Drive bays and front panel connectivity
Data storage has its own dedicated space in the hard drive cage and on mounting trays. The NZXT H9 Flow RGB+ PC case accommodates a total of two classic 3.5" hard drives and four 2.5" SSDs. A swing-out mechanism for the drive bracket makes access and installation easy. This capacity is fully sufficient for a combination of fast system drives and high-capacity data storage. The control panel, located on the top, provides quick access to all necessary ports. The equipment includes two USB 3.2 Gen 1 Type-A ports and one high-speed USB-C Gen 2×2 for lightning-fast data transfer. The connectivity is rounded off by a combined 3.5mm audio jack for connecting a headset. The layout of the connectors meets modern demands for ergonomics and accessibility.
