Fractal Design Define R4 review: refined silence
 

Fractal Design is known for creating computer chassis with an emphasis on silent cooling. The company has gathered a loyal following that appreciates the stylish design, quality materials and good performance of their products. We have frequently been very positive about their chassis, and some time ago the fourth edition of their "Define" flagship chassis was released, the R4. It took a while to arrive at our lab, but finally we are able to test the Fractal Design Define R4 and compare it to other silent chassis designs.
