Compact storage server chassis

The Silverstone SST-CS381B is a Micro-ATX and Mini-ITX case built for dense storage workloads. Its steel and plastic frame fits eight hot-swap bays in a short-depth layout suited to home labs or small business servers.

Eight hot-swap SAS/SATA bays

The defining feature is the front-mounted cage that accepts eight 3.5-inch or 2.5-inch drives with SAS or SATA interfaces. Drives can be swapped without tools or system downtime, a requirement for RAID arrays or ZFS pools.

Capacity headroom and limits

Four internal 2.5-inch slots add SSD space for boot or cache duties. A 59-millimetre CPU cooler ceiling and 266.7-millimetre GPU limit restrict high-performance parts, while the SFX power supply mount caps length at 200 millimetres.

Questions about this item

How much clearance does the 59 mm CPU cooler limit leave for a top-down cooler?

The manual requires at least 10 mm of space above the fan, so a top-down cooler must fit within 59 mm total height and still leave that gap for airflow.

What does the USB 3.1 Gen 1 front port actually deliver in practice?

The two front ports run at 5 Gbps USB 3.1 Gen 1 speed and also provide a combined audio jack for headset use.

What drive heights fit in the four internal 2.5" bays?

The bays accept 2.5" drives from 5 mm to 15 mm thick, with two of the slots located on the left-side racks.
