Define Nano S │Rethink Small.
Balancing size with silence
The Define Nano S is a great ITX solution for customers who want to create
enthusiast-level builds without sacrificing the features they are accustomed to having
in mATX or ATX cases.
Mirroring the layout first seen in the Define S, the Define Nano S is still roomy for its
small size with enough space for full-size components as well as a variety of air and
water cooling options. Its tower-like aspect ratio is unique within the ITX form factor,
allowing the freedom and flexibitily for users to build comfortably.
Above all, the Define Nano S offers users silent computing within the ITX form factor.
Featuring the same professional grade sound dampening material that is used in the
auto industry, the Nano S is an ITX chassis without compromise.
