Designed from the ground up, Fractal Design's 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.

Sound-dampened steel panels encase a fully redesigned interior with more storage capability than ever before, and with nine fan mounts, PWM fan hub, and 420mm radiator support, the R6 is the perfect platform for building your dream water loop. Improved third-generation ModuVent™ technology allows an effortless transition from metal-clad sound dampened top panel to filtered high airflow multi-fan ventilation.

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.
