Define R4

The Fractal Design Define R4 is the latest in the Define Series of computer cases offering minimalistic and stunning Scandinavian design fused with maximum sound reduction, configurability and functionality. The Define R4 side and front door panels are fitted with dense, sound-absorbing material making it a benchmark for noise reduction. Moreover, the Define R4 accommodates up to 8 HDDs, all modern graphics card sizes, and multiple ventilation options - including two standard Silent Series R2 hydraulic bearing fans - to keep internal components at optimal temperatures.

For ultimate functionality, the Define R4 features a front interface with USB 3.0 and an integrated threespeed fan controller behind the front panel door.

  • Top HDD cage (5 trays total) can be rotated 90 degrees or removed for additional airflow or to accommodate long graphic cards up to 430mm in length
