The HS 420 is a work of functional beauty and user-centred innovation. After dozens of prototypes and redesigns and literally thousands of hours of rigorous testing by HAVN and Pro Gamers Group engineers, we tailored this Hybrid Structure case to deliver unrivalled central GPU airflow in a dual-chamber design while maintaining traditional mid-tower dimensions. Built for the most powerful fans and radiators on the market, it offers the thermal optimisation needed for the most demanding tasks.
