    Fractal Design Define Series R6 Tower Product Description

    Designed from the ground up, the Define R6 goes beyond iteration with a profound stride of innovation - the latest and largest step in the legacy of the world-renowned Define Series.  

    Seamless tempered glass and sound dampened steel panels with an elegant push-to-lock latching mechanism encase an entirely redesigned interior with unprecedented component support and storage flexibility. Six 3.5"/2.5" drives and two 2.5" drives can be installed with precision placement in countless configurations throughout the case. 

    The spacious and fully adaptable framework of the Define R6 sports nine fan mounts, integrated PWM fan hub and support for radiators up to 420mm, making it the perfect platform for building your dream water loop. Improved third generation ModuVent™ technology allows an effortless transition from steel-clad sound dampened top panel to filtered high airflow multi-fan ventilation setup. 

    Expanding on the timeless elegant form and silent modular function that brought so much success to its predecessors, the new Define R6 offers the most demanding hardware enthusiast a solid foundation and flexible framework with limitless potential.
