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.
