Fractal Design's Define S is a leaner, meaner R5

Fractal Design is expanding its Define series with a new model, the Define S. This case maintains the understated design that we've seen from the company's other enclosures, like the Define R5, but Fractal has made some big changes inside.

Most notably, the Define S completely dispenses with the R5's modular drive cages. Instead, Fractal puts three 3.5" drive mounts behind the area where those cages would typically reside. This design leaves an unobstructed airflow path for the main components in the system.

In place of the drive cages, Fractal includes a couple of liquid-cooling-friendly features. There's a pegboard-like area in front of the motherboard tray for coolant reservoir mounting, plus a set of pre-drilled pump holes on the floor of the case. The Define S keeps the R5's 420-mm radiator mount up top and 360-mm radiator mount up front, so it looks like there's plenty of room for internal heat exchangers.

This new Define is priced at $79.99, versus the R5's $109.99 base price. Despite the lower sticker, Fractal still includes a lot of the trademark features we liked in the Define R5, including noise-insulated side and top panels. The R5's modular top panels stick around, as well.

We have a Define S on the way to our labs for review. Keep an eye out for our in-depth look at this new case.
