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 eight 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 three-speed fan controller behind the front panel door. This case is available in Black Pearl, Titanium Grey and Arctic White.


Optimal Noise Reduction

The case uses high density noise-reducing material bitumen on the front and side panel for amazing noise absorption.

ModuVent Design

Exclusive ModuVent design allows user to choose between optimal silence and maximum airflow. The Define R4 is equipped with ModuVent plates (two in the top and one in the side). If cooling becomes more of a priority than noise reduction, the ModuVent panels can be removed to expose additional air vents for optional fans.

HDD trays (all compatible with SSDs) and eight expansion slots offer amazing expandability. Two SSDs can also be mounted on the back of the motherboard plate.
