Product information

Description

The Silverstone CS381 Micro ATX Black is a compact desktop chassis designed for Micro ATX, Mini-DTX and Mini-ITX motherboards. Measuring 400mm (W) x 316mm (D) x 225mm (H), this small form factor case supports SFX power supplies and offers flexible storage and cooling configurations. The case comes in a matte black finish and includes two pre-installed 120mm rear fans, while additional side fan mounts accept 80mm or 120mm fans. Drive compatibility covers both 3.5" and 2.5" HDD/SSD sizes to suit a range of storage setups.

Advantages

The case combines a compact footprint with support for multiple drive bays, allowing users to pack high storage capacity into a small enclosure without sacrificing compatibility with Micro ATX components. Pre-installed rear 120mm fans provide immediate airflow, and the option to add 80mm or 120mm side fans enables targeted cooling for hot components. Built from metal and plastic, the Silverstone CS381 balances structural rigidity and weight, while front-panel USB 3.2 Gen 1 Type-A ports provide modern connectivity for peripherals and external drives.

Suitable for

Home or office systems where desk space is limited
Compact gaming builds using Micro ATX or Mini-ITX motherboards
NAS-style storage systems or backup servers with multiple hard drives
Small workstations for light content creation or CAD with discrete cooling options

Dimensions (W x D x H): 400mm x 316mm x 225mm
Drive bays: supports multiple 3.5" drives and 2.5" drives
Pre-installed cooling: two 120mm rear fans
Additional fan support: side mounts for 80mm or 120mm fans
Power supply type: SFX-compatible (power supply not included)
Front-panel I/O: two USB 3.2 Gen 1 Type-A ports
Material: metal and plastic construction
Colour: black; approximate weight: 7 kg

How to use

Install a compatible Micro ATX, Mini-DTX, or Mini-ITX motherboard onto the included standoffs and secure with screws. Mount an SFX power supply in the designated compartment and route cables through the case openings to the motherboard and drives. Populate drive bays with 3.5" or 2.5" HDD/SSD units using the supplied brackets or trays, and connect drives to the motherboard and power supply. Use the pre-installed rear 120mm fans for exhaust airflow and, if required, install 80mm or 120mm side fans to direct intake air toward storage or GPU areas. Connect peripherals to the front-panel USB 3.2 Gen 1 ports for fast external storage access and device connectivity.

Usage recommendations

For optimal cooling in compact builds, configure at least one side fan when using multiple 3.5" drives or a discrete graphics card. Use high-quality SFX power supplies to ensure stable power delivery, and route cables neatly to maintain unobstructed airflow. When building a storage-focused system, prefer 2.5" SSDs for lower heat output or add side ventilation if many 3.5" drives are installed.
