Build a quiet and clean system with the Fractal Design Define R6 Midi Tower Case, featuring sound‑dampened steel panels and a reversible anodized aluminum front door. It supports E‑ATX, ATX, micro ATX, and Mini‑ITX motherboards, and comes with nine fan mounts, an integrated Nexus+ fan hub, and flexible storage options (six 3.5″/2.5″ + two 2.5″). Its modular interior, open‑layout capability, and radiator support (up to 420 mm) make it ideal for both silent computing and high‑performance water‑cooled builds
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 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.
