Compact 28-litre Micro-ATX server chassis holds eight hot-swap 3.5" or 2.5" SAS-12G/SATA-6G drives with dual LEDs and two 120mm dual ball-bearing fans
The Silverstone CS381 is a 28-litre rackmount chassis that supports micro-ATX, Mini-DTX and Mini-ITX motherboards. It provides eight front-accessible hot-swap bays for 3.5-inch or 2.5-inch SAS and SATA drives. Two 120mm dual ball bearing fans with a 70,000-hour L10 rating are included for cooling. The case also accepts SFX or SFX-L power supplies.
This chassis suits builders who need eight hot-swap drive bays in a small footprint and want the flexibility of vertical or horizontal placement. It also accommodates a 240mm liquid cooling radiator and full-height expansion cards up to 267mm long. Buyers requiring more than eight external bays, internal 5.25-inch bays or support for larger ATX motherboards should consider other form factors.
The defining specification is the eight front hot-swap trays that accept both 3.5-inch and 2.5-inch drives running on SAS-12G or SATA-6G interfaces, each with dual LED status indicators. This bay count and interface combination determines whether the chassis matches the storage density and protocol requirements of the planned NAS or server deployment.

It supports Micro-ATX, Mini-DTX and Mini-ITX boards and takes an SFX or SFX-L power supply.
Slide each tray into the front bay until it clicks; the step often missed is fully seating the tray so both SAS-12G / SATA-6G LED indicators light up.
The two included 120mm dual ball-bearing fans are rated L10 70,000 hours; expect to replace them once they become noisy or airflow drops.
