Fractal Design Define R4 Case Review

Overall we are very impressed with the Fractal Design Define R4. It is one of the finest cases you can buy at around £100.

The minimalist design and the brushed aluminium effect front panel means it could easily be mistaken for one of Lian Li’s models. Obviously it is sold at a much cheaper price tag as it’s constructed from steel rather than aluminium. Even though it is constructed from Steel, build quality is excellent.

We would say it offers a similar level of build quality to cases from Corsair with the added benefit of extensive sound deadening. The excellent acoustic performance of this case is sure to be a key selling feature as it’s one of the quietest mid-tower cases available on the market.

It’s very difficult to find fault with the Define R4.  The only issue that might affect some users is the fan spacing in the roof of the case.  The mounting holes aren’t positioned in the correct place to install a Corsair H100 which will disappoint some enthusiasts.

If we were being very picky, we would say that the plastics used for the front panel of the case behind the door feel a little on the flimsy side.

The Fractal Design Define R4 can be yours for £100 from Overclockers UK.  At this price we think it offers great value for money and should be the first consideration for anyone looking to build a quiet but powerful air-cooled mid-tower system.


  • Sleek design.
  • Impressive build quality.
  • Plenty of storage options.
  • Very quiet indeed.
  • Extensive cable routing provision.
  • Good value.


  • Not suitable for water cooling.

KitGuru says: An excellent case which is whisper quiet and well built.
