The Fractal Design Define R4 is the midi tower in the Define Series of computer cases offering minimalist and stunning Scandinavian design fused with maximum sound reduction, configuration 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 three-speed fan controller behind the front panel door.


Pre-fitted with dense noise-absorbing material, the R4 also features ModuVent panels which prevent noise from escaping unused fan vents when silence is required. If cooling becomes more of a priority than noise reduction, the ModuVent panels can be removed to expose additional air vents for optional fans.


You no longer have to make the choice between liquid cooling and silence, the R4 offers both. Top fan positions now allow slim 240mm radiators to be mounted. Select slim radiators can be mounted in the front fan holder (requires the bottom HDD cage to change position).


Hide those drives! Take cable management and interior cleanliness to a whole new level. Mount up to two 2.5in, SSDs out of sight on the back side of the motherboard tray.


Fan control at your fingertips. The integrated fan controller is easily accessible behind the front panel and manages up to three fans, allowing you to tailor the fan speed to your needs.



Configuration flexibility is enhanced thanks to two hard drive cages (featuring steel drive trays with black silicone mounting grommets) that support a total of eight 3.5in. HDDs or 2.5in. SSDs. The top five-bay cage is easily rotatable and removable; removing the top cage allows support for graphics cards up to 470mm in length. The bottom three-bay cage is mounted to the chassis by screws instead of rivets, allowing you to easily remove both drive cages for complete flexibility.


Over 1in. of space behind the motherboard plate means cables can be conveniently routed through five rubber grommets into a generous compartment behind the motherboard to reduce cable clutter and improve airflow.

Features & Benefits

  • High density noise-reducing material for an optimal silent case - To achieve a high level of noise reduction, material with mass should be incorporated which is what we strive to achieve with the dense bitumen used on the side panels.
  • Patent pending ModuVent™ design allowing the user to choose between optimal silence or maximum airflow.
  • 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.
  • Three-speed fan controller is strategically integrated in the front panel and supports up to 3 fans.
  • Two Silent Series R2 fans included, featuring hydraulic bearings contributing to a longer life expectancy – Silent Series R2 retail fans will now come standard in all cases.
  • Wider case body that allows for improved cable routing behind the motherboard – now 26mm wide.
  • New tool-less front fan holder makes switching front fans a breeze.
  • Two SSDs can be mounted on the back of the motherboard plate in addition to the 8 slots in the HDD trays, for a total of 10 SSD positions available.
