## Long description

The Fractal Design Define Nano S - Window is a compact Mini Tower ITX case engineered for efficient airflow and quiet operation. Finished in black, it supports ATX power supplies, accepts full-size high-performance components in an ITX layout, and includes one 140 mm front fan and one 120 mm rear fan. The case offers removable dust filters on the front and bottom intakes, a side window for component visibility, and mounting options for simultaneous radiators to enable effective cooling of enthusiast-level systems.
Advantages
The case combines an ATX-like internal layout in a small Mini Tower footprint, enabling installation of full-size components while preserving a compact external size. Integrated sound-dampening material and Fractal Design’s ModuVent™ top vents reduce noise without restricting cooling options. Removable dust filters and an unobstructed airflow path simplify maintenance and help keep internal temperatures low.
Suitable for
 Compact gaming or high-performance ITX builds
 Silenced home or office PCs where low noise is important
 Systems requiring multiple storage drives (2.5" and 3.5")
 Builds with water cooling using simultaneous radiators

Usage recommendations
For quiet operation while maintaining cooling performance, use the case’s ModuVent™ panels in a partially open configuration combined with the supplied front 140 mm fan and a low-noise CPU cooler or AIO radiator.
