Product identity

The In Win IW-SK34-02.H is a 3-in-4 storage kit that converts three standard 5.25" drive bays into four hot-swap trays for 2.5" or 3.5" drives. It is built for server administrators who need dense SAS or SATA storage in a compact front-loading form factor.

Who it suits

This kit suits builders who want to populate multiple 5.25" bays with removable SAS and SATA hard drives and who value the front indicators that signal fan failure or temperature spikes. Buyers who need support for protocols other than SAS and SATA should look elsewhere.

Deciding specification

The detachable 90mm PWM rear cooling fan provides active airflow directly across the four drive trays. If your chassis cannot accommodate a rear-mounted fan in this position or relies solely on passive cooling, this accessory will not fit the thermal design.
