The Fractal Design Define S lends the appearance, sound dampening technology, and support for a wide variety of components from the widely popular Define Series, while introducing a new, innovative internal layout. The Define S case is packed with intelligently designed enthusiast-oriented features delivering a silent case with powerful and expansive air and liquid cooling support, presented in a stunning Scandinavian inspired construction.


The modernized internal layout of the Define S omits the optical drive bays, instead focusing on a clear straight airflow path and uncompromising water cooling support.


The Define S case reaches the highest level of silent computing through strategically placed dense sound-absorbing material, multiple ModuVent™ fan vent covers and finely tuned Dynamic Series fans.

KitGuru - Best Of 2015

"That kind of space will allow you to fit a pair of large radiators (420mm in the roof and a 360mm in the front) – ideally with mounts that are offset to help you clear the mainboard – as well as quality cushioning for your power supply and Velcro cable straps for better management. Enter the Fractal Design Define S."

Well built, nice finish and very spacious

by DBT85 star star star star star

Bought one as a precursor to a watercooled build so for the moment it's only got air cooling inside.The finish on all the metal is very nice, no sharp bits, nice grommets in the right places.Most importantly, nothing getting in your way in the main compartment so loads of room for some a nice pair of rads and everything else.
