Fractal Design Define S Midi-Tower Case with window, Black

The Fractal Design Define S is a Midi Tower case engineered for quiet operation and high-airflow configurations. Its internal layout is optimized by omitting optical drive cages, which creates an unobstructed path for air to travel from the front intake to the rear exhaust. The chassis is constructed from steel and incorporates sound-dampening material on the right-side panel to reduce system noise. A large window panel provides a clear view of the internal components and the overall build.

This case offers extensive support for both air and liquid cooling systems. It features a total of eight fan mounts and dedicated locations for radiators on the top, front, rear, and bottom panels. The interior accommodates ATX, Micro-ATX, and Mini-ITX motherboards, with ample clearance for tall CPU air coolers and long power supply units. For initial cooling, two 140 mm Dynamic Series fans are pre-installed. The design also includes dust filters for the front and bottom intakes, along with fixed velcro straps for cable management.
