FRAME Modular Case System - The revolutionary FRAME system gives new meaning to the word customization. Some of the choices include upgrading the motherboard tray to billet aluminum, replacing the front I/O panel with different USB ports, and swapping out the front intake panel for a different look. This case evolves with your needs, offering a variety of options for future upgrades and aesthetic changes. Clean Lines or Turbo Cooled – The internal side panel near the motherboard tray can be used as a cable cover for clean cable management, or you can remove it and mount fans to the side for increased cooling potential. 3D Y-Pattern Airflow Panel – Optimized for high airflow and minimal restriction, the steel front panel is perforated in three dimensions with a Y-pattern that provides a low-obstruction path for cool air. Top 420mm Radiator Support – Take your cooling to the next level with a top-mounted 420mm radiator and room for 360mm radiators on the front or side. InfiniRail Fan Mounting Options - Mount up to 14x 120mm fans simultaneously to keep cool air flowing in and hot air exhausting quickly and efficiently, or easily adjust the InfiniRail fan mounts for 140mm or 200mm fan locations. The combinations are nearly endless.
