HAVN Hybrid Structure for Optimal GPU Cooling

Dual chamber design with balanced airflow and traditional case size ratio, designed to direct cool air from the bottom intake to the centrally located GPU.

GPU-centric design

The GPU is at the heart of the HAVN hybrid structure, fully showcasing it behind the panoramic UniSheet glass. This design optimizes the airflow of the GPU and highlights the most important components.

Mirror airflow

An additional fan intake at the bottom of the rear side channels cool air directly to your graphics card, perfectly balancing intake and exhaust. This ensures maximum performance and helps maintain a cleaner, dust-free system.

The HS 420 can accommodate a total of eleven 140mm fans and supports radiators up to 420mm at the top, right, and bottom.

UniSheet thermoformed glass panel for panoramic view

We challenged the limits of manufacturing to design the smallest possible curve radius and minimize visual distortion, providing the user with a clear and continuous view of the interior of the case.

Unique SimpliCable Routing System

Uniquely user-friendly SimpliCable routing system and fan hub - the grooved guides from top to bottom neatly route your cables for a flawless overall appearance.

Reinventing Cable Management

The smart silicone grommets with stabilizing clips allow for precision cable management.

Vibration Isolation

All fan mounts feature flexible rubber to isolate the mount from the chassis and prevent resonance.

GPU Support

The adjustable 3-way structural support bracket is designed to handle a wide range of graphics cards of all shapes and sizes, while maintaining a neat and smoothly integrated appearance.

    I saw the case months ago and I liked its appearance. I also saw some reviews and fortunately, apart from the looks, it is also very good in terms of features.
    Definitely built for custom loops and multiple radiators, I have only installed an Arctic 420 for the processor on top, and 140mm fans in the other positions.
    So far, during the tough Greek summers, it performs well in terms of temperatures, with a relatively quiet fan profile.
    Heavy and quality case, I agree that with its size it could have had more cable management space. I was also considering extensions mainly for aesthetic reasons, but since I didn't have the patience when I built it, I stuck with the be quiet cables from the power supply.
    It would also be nice if the included accessories and screws were in a plastic box like Phanteks used to do (I don't know if they still do it).

    Very spacious case and incredibly high quality. Of course, at this price you wouldn't expect anything less. Since almost everything can be removed, it is very convenient for installing fans and AIO. The 120mm fans look small, so I would suggest using 140mm, since it fits 3x140mm on the top, bottom, and side, as long as you remove the HDD cages. The grommets and the channels for routing cables are very convenient. I have no issues with airflow (compared to the Lian Li Dynamic 011 I had before, temperatures are lower). The only "negative" I found is that, since I use extension cables for my PSU, it took me many hours of cable management to fit everything and close the back panel without it bulging.
    Therefore, for its size, it could have a bit more space for cables.

    Very easy in everything, building, cleaning, cable management.
    I am a bit concerned about the CPU temperature but I believe that something else is to blame and not the case.

    -: Quite heavy, the bottom filter has a poor fit, be careful with cable management at the back as there is limited space
