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.


  • 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

  • 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

4* Fractal R4 - good, but snags on quality
Reviewed by Ian on 25/11/2012
Impressed by strength and design of this case, built from heavy gauge steel, well fitted together, easy to work on, and looks good. One drive cage removes completely, which helped route cabling just where I wanted it, and all bays have separate removable trays, so putting drives in is very easy. Sound insulation is good, the only noticeable noise is from the fan at the back and that's not at all intrusive (I have a BeQuiet 530W power supply in the case, which is very quiet). Some difficulties with the build quality, though. Motherboard stand-offs very tight in their holes and alignment with holes in motherboard not spot on, which caused some difficulty. Also one of the side panels proved so difficult to remove I've decided not to seat it fully back in place, because I nearly pulled my fingernails out getting it off (other side panel was fine though). Overall a very good case, slightly let down by the quality issues.
3* Fractal R4 - looks good, HDD cage vibrates like crazy
Reviewed by ZED on 23/10/2013
I love the plain and simple look of the case, the very reason i brought one! there's tons of space to work with, cable management is brilliant. build quality is very good.

The only thing that's annoying the living daylights out of me is the HDD cage/bay vibration which is buzzing like crazzzzzzyyyyyy when the HDDs are spinning!!! it's unbearable, I've tried to remedy the problem by tightening the bay/cage screws but its just not having it!!!!

To pay a premium for such a case is just not worth it!
