Product Information

The Define Nano S is an ITX case that features compatibility with high end, full-size components, superior sound dampening, and an ATX-like layout.

The case includes two Dynamic Series fans with both bottom and front intakes protected by easy-to-clean, removable dust filters.

With its mounting capabilities for simultaneous radiators and unobstructed airflow path, the Define Nano S can cool enthusiast-level components.

Equipped with Fractal Design’s signature ModuVent™ technology on the top vents and sound dampening throughout, the Define Nano S can run a powerful system quietly, a hallmark of the Define series.
