The Define S2 is the latest leap forward in open-layout case design—an ingenious refinement of the zero-obstruction formula that cemented the series as the de facto standard for the silent high-performance build.
The S2 achieves increased cooling capacity with nine fan mounts and support for pumps, reservoirs and large multi-fan radiators in the top, front and base. An innovative removable bracket with built-in fill port offers easy access directly through the top of the case, while third-generation ModuVent™ technology with industrial sound dampening maintains quiet operation.
Full USB 3.1 Gen 2 Type-C comes standard along with three Dynamic X2 fans, full-length PSU shroud and support for vertical GPU installation via the Flex VRC-25 riser, available separately.
Whether your aim is silence, efficiency or sheer water-cooled extravagance, the Define S2 hits the mark.
