HAVN HS 420 Mid-Tower PC Case — Black
The HAVN HS 420 is a work of functional beauty and user-centric innovation. Developed through dozens of prototypes, redesigns, and thousands of hours of rigorous testing by HAVN and Pro Gamers Group engineers, the HS 420 features a patent-pending Hybrid Structure that delivers 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 needed for the most demanding builds.
Key Features
- HAVN Hybrid Structure dual-chamber design — directs cool air from the bottom intake onto the centrally positioned GPU for optimal GPU thermals
- GPU-centric layout — GPU takes center stage behind the panoramic UniSheet glass for maximum visual impact and airflow
- UniSheet heat-formed panoramic glass — front and side panels with the smallest possible curve radius to minimize visual distortion
- Supports up to 11 fans total — optimized for 140mm fans; 3 positions each on top, right, and bottom; 2 on the rear
- Up to 420mm radiator support on top, right (side), and bottom simultaneously
- Mirrored airflow — rear bottom fan intake channels cool air directly to the GPU for balanced thermal performance
- SimpliCable routing system — top-to-bottom grooved guides and silicone pass-throughs cleanly route all cables
- Integrated dual PWM fan repeaters (12 ports total, 6 per repeater) — reduces fan cable clutter
- 3-way adjustable GPU structural support bracket — tool-free, handles cards of all shapes and sizes
- Vibration-isolated fan brackets — flexible rubber isolators on all fan mounting points
- VESA display mount (75×75 / 100×100mm) for up to 14" internal display in front right pillar
- Supports E-ATX / ATX / M-ATX / Mini-ITX motherboards
- GPU clearance up to 480mm length / 195mm width
- CPU tower cooler up to 185mm (liquid cooling recommended)
- ATX PSU up to 220mm
- Front I/O: USB 3.2 Gen 2 Type-C, 2× USB 3.2 Gen 1 Type-A, Audio Jack, Power & Reset
