HS 420
The HS 420 is a work of functional beauty and user-centric innovation. Through dozens of prototypes and redesigns, and literally thousands of hours of rigorous testing by HAVN and Pro Gamers Group engineers, we have tailor-made this Hybrid Structure case to deliver unrivaled central GPU airflow within a dual chamber design while maintaining traditional mid-tower dimensions. Built for the most powerful fans and radiators on the market, it provides the thermal optimization you need for the most demanding tasks.
- UniSheet heat-formed panoramic glass panel for front and side, engineered to be flatter and with a smaller radius to minimize visual distortion.
- Optimized thermal performance design with custom panel ventilation, ideal for 140mm fans (11 fan positions in total), and up to 420mm radiators on the top, side, and bottom.
- Intuitive SimpliCable routing system & fan hub organizes your cables cleanly and discreetly.

HAVN Hybrid Structure for Optimal GPU Cooling
Dual-chamber design with balanced airflow and a traditional case size ratio, designed to direct cool air from the bottom intake onto the centrally positioned GPU.
GPU Centric Design
The GPU takes center stage within the HAVN Hybrid Structure, putting it on full display behind the panoramic UniSheet glass. This design optimizes GPU airflow and highlights your most important components.
Mirrored Airflow
An additional fan intake at the bottom of the rear panel channels cool air directly to your graphics card, perfectly balancing intake and exhaust. This ensures peak performance and helps maintain a cleaner, dust-free system.
Cooling Power & Compatibility
HS 420 fits a total of eleven 140mm fans while supporting up to 420mm radiators on its top, right, and bottom.
UniSheet heat-formed Glass Panel for Panoramic View
We challenged the limits of production to engineer the smallest possible curve radius and minimize visual distortion, providing the user with a clear and continuous view of the inside of the case.
Unique SimpliCable Routing System
Uniquely user-friendly SimpliCable routing system and fan hub - top-to-bottom grooved guides cleanly route your cables for a pristine overall appearance.
Cable Management Re-Invented
Clever silicon pass-throughs with stabilizing clips allow for precision cable management.
Vibration Isolation
All of the fan brackets have flexible rubber to isolate the bracket from the chassis and avoid resonance build up.
GPU Support
The 3-way adjustable 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.
Customization
Customizable space accommodates a combination of storage, fans, radiators, and portable displays (VESA mounting bracket included)

Ive had my fair share of fancy corsair cases, built in hyte, fractals etc. This one though. Takes the crown. Excellent build quality. Well thought out cable routing thats even labeled for recommendations. Each fan spot being 140mm makes this case breathe much better than most while being very quiet. Its far from cramped, super easy to build in. I would buy this again.
Found this case while watching Gamers Nexus. Largest case I’ve built in yet but I knew that going in. First off, amazing user guide for beginners and experienced pc builders alike. It’s a big case with lots of features, so the step by step guide with ACCURATE AND DETAILED images and descriptions is appreciated. Lots of space to work with and it makes installing parts much easier. Cable management channels in the rear of the case are very helpful (especially with the recommended cable labels). The customizability of the storage bay space is a nice example of this case being for anyone. Can be fans, extra storage, or an internal display screen with the provided mount. The curved glass is amazing looking making it look like a proper display for the components inside. My only complaint is how heavy the case is because once you get your parts in be careful not to underestimate it when you need to move it around for maintenance. 10/10 and looking forward to other products in the future.
Beautiful case and easy to install components. Its a clean build with room for all my devices. Again, just a beautiful case.
Was a joy building using the HS 420. Not only is it aesthetically pleasing. It's easy to work with. The build in cable management system is top notch. One thing to note is this case is heavy and quite big. It's on the larger end of Mid Tower cases.
I would highly recommmend it!
The HS 420 is undoubtedly a labor of love. The curved glass is next level design and building in this case is simply a joy. I can't wait to see what HAVN has coming next.
I like this case when I first heard about it. Very nice case! I am considering a custom hard tube water cooling with this case.
It's the little things, every little thing I want to do in the case was thought of and thought out. Its amazing how well this was done. A really good example, the door is a massive gorgeously curved piece of glass, so its heavy and scary to remove. When you pull it off you have to move it to the right as it locks in place on the wall of the case with Magnets, screws, and finally, a hook mount just to make sure if it slips at all it slips into place and not onto the floor. There are examples all over the case of thought and care into making this just a dream to work in. Please keep designing cases, as I will absolutely be a repeat customer.
Love the case. Easy to build in and great for cable management!
Really impressed with the build quality and the ease of access for most everything. Couldn't be happier to have bought these for my builds!
