Fractal Design Define S Review

(19 Comments) »

Introduction


I would like to thank Fractal Design for supplying the review sample.


Fractal Design is adding to the Define family with the Define S chassis. Having reviewed every R series chassis the company has ever produced, it is great to see such an evolution as the Define S specifically tailored around housing custom liquid-cooling loops. While Fractal Design cases generally play well with radiators, most of them do not offer dedicated mounting possibilities for the other two major parts in a custom loop: pumps and radiators. This is where the Define S comes into play.

Packaging


The Fractal Design Define S ships in a brown cardboard box with a drawing of the unit on the front and details on its features on the back. Both sides also come with carrying holes, an additional image of the chassis, and a list of specifications.


Two sturdy Styrofoam spacers hold the entire unit in place and protect it from damage during shipping, while a plastic bag has been applied to keep scratches and fingerprints away.
