Description
Build a powerful, compact PC without compromising on features with the Fractal Design Define Nano S Mini-ITX Computer Case. Designed for enthusiasts who want the flexibility of a larger ATX or micro-ATX-style layout in a smaller footprint, the Define Nano S combines a spacious interior, sound-dampening materials, and versatile cooling support in a distinctive tower-style design.
Inspired by the internal layout of the Define S, the Define Nano S accommodates full-size components within its Mini-ITX form factor. Its open interior promotes unobstructed airflow from the front intake toward the rear exhaust, while support for multiple air and liquid cooling configurations gives builders the flexibility to create a performance-focused system.
With Fractal Design's signature sound-dampening materials and ModuVent™ technology, the Define Nano S is built for users who value quiet operation alongside enthusiast-level hardware and cooling options.
