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)

Customer Reviews
HAVN has done an incredible job with the build quality and enthusiast features of this case. The glass is stunning. There are a bunch of build quality of life features that are great like cable management, custom wire brackets, fan headers and a ton of space for the largest radiators and video cards.
Case has the aesthetics and great cable managment, would buy again
The build quality is astounding. And overall beautiful case.
Love the look, construction and design of the case. Made cable management easy and keeps my cpu and gps cool as a cucumber
The curved glass looks amazing. Easy to assemble especially if this is your first build. Very easy to access all 4 sides of the case.
This PC Case is QUALITY. It is hefty than a lot of my previous build but there is a lot of attention to detail with this case. I'm using this case to air cool (no AIO) and its been about a week. Temps are great and I honestly love the aesthetic of this case. Out of all the PC builds.. This PC case made it fun.
Best case I’ve purchased. Case was delivered quickly and had well documented instructions. Would definitely recommend to enthusiasts who want a well constructed case.
This thing is MASSIVE. Like actually it arrived on my doorstep and I thought they sent me the wrong package. But no, it is the case, and yeah the case is amazing. Opening it is legitimately an experience, and the details they include tie it all together. Worth every penny and I would gladly build in it again, bravo HAVN.
This is the best to build in and with room for 11x 140 fans the thermal headroom is fantastic.
Very solid and well built case for the money. Plenty of room for 420mm radiators top side or bottom without motherboard clearance issues like some other cases that claim 420 support. Very easy build with the removable fan trays and cable routing and the amount of access you get with the glass panel off.
