SilverStone CS381 Micro-ATX Storage Server Chassis, 8x Hot-Swap 3.5 inch Bays, Black

The SilverStone CS381 stands apart from typical micro-ATX towers by packing eight hot-swappable 3.5" drive bays into a compact chassis built for serious storage. It supports micro-ATX, Mini-DTX, and Mini-ITX motherboards, with a steel body and plastic front panel finished in black. Two rear 120mm fans are included, and the front panel features a key lock for physical security.

Highlights

• 8 x 3.5" hot-swap bays with SATA/SAS backplane
• 2 x internal 2.5" drive mounts
• 2 x USB 3.0, headphone and microphone ports
• Supports SFX and SFX-L power supplies (max 130mm)
• Dust filters on front, side, and top

In daily use

The CS381 suits home servers, NAS builds, or small office storage. Drive swaps are tool-free thanks to the hot-swap backplane. With all 3.5" bays populated, CPU coolers up to 59mm and GPUs up to 267mm fit; removing the drive cage allows 147mm coolers and 349mm graphics cards. A 120mm radiator can replace the rear fan if liquid cooling is preferred.
