Some marketing info first. The model was officially introduced on 3 November 2023.


“The H6 Flow offers a harmonious blend of performance and visual appeal for PC enthusiasts. Designed for an expansive and uninterrupted view, the H6 Flow is adorned with consistent tempered glass on the front and sides, granting a panoramic peek into the insides of your build. Leveraging its dual-chamber architecture, the new angel front panel directs the airflow from the three pre-included 120 mm fans (or 120 mm RGB fans for the H6 Flow RGB version), and two 140 mm fans at the base of the case allow you to cool your heat generating components. The revamped perforated panels come with a design fine-tuned for optimal airflow and superior performance. While all easy to build, the H6 Flow facilitates generous cable-routing channels and straps, ensuring organized cable management.

  • High-Performance Airflow: The top and side panels feature an airflow-optimized perforation pattern to enhance overall performance and filter dust.
  • Quality of life features: Tool-free access to the top and side panels makes upgrading quick and convenient and an intuitive cable management system simplifies the build process by using wide channels and straps.
