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.
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.
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.
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.
HS 420 fits a total of eleven 140mm fans while supporting up to 420mm radiators on its top, right, and bottom.
We've pushed production boundaries to achieve the smallest possible curve radius, minimizing visual distortion and offering a clear, uninterrupted view of your case's interior.
The SimpliCable routing system and fan hub feature top-to-bottom grooved guides, making cable management effortlessly clean and giving your setup a pristine, organized appearance.
Clever silicon pass-throughs with stabilizing clips allow for precision cable management.
Every fan bracket is equipped with flexible rubber isolators to separate the bracket from the chassis, preventing resonance and ensuring a quieter operation.
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.
