Overview:

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.

Features:

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)
