  • Front. NZXT - H9 Flow ATX Mid-Tower Case with Dual Chamber - Black.
  • Alt View 11. NZXT - H9 Flow ATX Mid-Tower PC Case with Dual Chamber - Black.
  • NZXT H9 FLOW Spacious mid-tower case featuring a high-airflow top panel, expansive cooling capacity, and a unique wraparound glass design.
  • High-Performance Airflow: Perforated top and side panels direct filtered air through the case to cool down components and enhance performance. Included 32 - T3 4 x 120mm fans.
  • NZXT DUAL-CHAMBER DESIGN: Cables, storage, and PSU are separate from other components to maintain a clean look and maximize airflow to the GPU.
  • The text on the image is already grouped and correctly written. It reads: "ENORMOUSLY COOL Supports radiators up to 360mm in the top, side, and bottom panels. Fits up to 10 X 120mm fans, or 6 X 140mm fans plus 1 x 120mm fan."
  • The storage solution showcased in the image is a hinged SSD wall panel that allows for easy access and installation of up to 4x 2.5in SSDs. Additionally, there is a separate bracket that can hold up to 2 x 3.5in HDDs. This setup provides a convenient and organized way to store and manage storage devices.
  • Easily Route Cables: Wide cable channels with hooks, bridges, and straps take the guesswork out of organized cable management.
  • The image features a computer case with a purple background and a black and white design. The case is designed to fit all NVIDIA GeForce RTX 40 Series GPUs and comes with a vertical GPU mount. The case is advertised as being ready for performance and is suitable for displaying the GPU vertically using the NZXT Vertical GPU Mounting Kit, which is sold separately. The case has a clearance of 435mm, and customers may need to request a free additional support piece from NZXT.com to support the H9.

    Very good case, comes with 4 fans. 3 on the side linked together and one exhaust fan. If getting this case I recommend an AIO for the CPU. My temps are CPU: 70-78 and GPU: 55-65

    Decent PC case, gives you a nice view to your PC. Depending on how often you clean your PC I'd recommend looking at other options. Removing the side glass panel can be annoying.
