NZXT H6 Flow RGB Review: A Stylish, Cooling-Optimized ATX Case



Choosing the right computer case is critical for builders who want to ensure their PC runs efficiently, stays cool, and looks great. The NZXT H6 Flow RGB is designed with these principles in mind, providing a compact, solidly built ATX chassis that boasts unusual cooling and excellent visibility into your PC’s pride and joy. Sized and styled to sit prominently on your desk, the H6 Flow RGB stands out with its unique design, customizable RGB lighting, and versatile airflow options. In this review, we’ll dive into its design, features, and cooling capabilities to see if it’s the right choice for your next PC build.


Design and Build Quality

The NZXT H6 Flow RGB exudes style and quality with its robust steel frame and tempered glass side panel. The front panel features a perforated mesh design that promotes airflow while maintaining a sleek appearance. The tempered glass side panel provides a clear view into the internals, showcasing your components and RGB lighting setup.

The case is solidly built, with tool-less panels and well-placed cable management channels that make assembly a breeze. The matte black or white finish options offer a minimalist look that easily blends into any environment. The case is designed to sit prominently on a desk, making it an attractive showcase for RGB lighting and premium components.

Interior Layout and Features

Inside the H6 Flow RGB, you’ll find a spacious and well-thought-out layout that accommodates ATX, Micro-ATX, and Mini-ITX motherboards. The interior provides ample clearance for large graphics cards up to 400mm long, CPU coolers up to 180mm tall, and power supplies up to 210mm deep.

Drive bays include two 3.5-inch and two 2.5-inch mounts, which are sufficient for most builders. The PSU shroud hides cables and power supplies while providing extra space for tidy cable management. The case also includes removable dust filters to keep your components clean and free of debris.

The front I/O panel is conveniently located and offers two USB 3.0 ports, one USB 3.2 Gen 2 Type-C port, and audio jacks for quick access to peripherals.

Cooling and Airflow

Cooling is where the NZXT H6 Flow RGB truly shines. The front panel’s mesh design promotes unobstructed airflow into the case, while the top and rear panels offer multiple mounting points for fans or radiators. The case comes pre-installed with two Aer F120 RGB fans, one at the front and one at the rear, providing immediate cooling out of the box.

For builders looking to customize their cooling setup, the case can accommodate up to six fans:

  • Front Panel: Up to three 120mm or two 140mm fans.
  • Top Panel: Up to two 120mm or two 140mm fans.
  • Rear Panel: One 120mm fan.

Radiator support includes a 360mm radiator at the front, a 280mm radiator at the top, and a 120mm radiator at the rear, making it an excellent option for custom liquid cooling or AIO coolers.

The case’s mesh filters are easily removable for cleaning, and the bottom-mounted PSU shroud includes a dedicated filter for additional dust protection.

RGB Lighting

The RGB setup on the H6 Flow RGB is both functional and customizable. The two included Aer F120 RGB fans are compatible with NZXT’s CAM software, allowing builders to synchronize lighting effects across their system or customize each fan individually. The RGB controller included with the case simplifies connectivity, while additional lighting strips or fans can be easily integrated.

Cable Management

Cable management is often an overlooked aspect of PC building, but the H6 Flow RGB makes it easy to keep cables tidy and organized. The PSU shroud hides excess cables, while the interior includes dedicated routing channels, Velcro straps, and cable ties to keep everything in place. The ample cable management space behind the motherboard tray ensures that even builders with complex configurations can maintain a clean look.
