SilverStone SST-RM31-MINI Rack 3U

The SilverStone SST-RM31-MINI is a compact 3U rackmount chassis engineered for high-density server and professional workstation deployments. Built from durable steel, it offers structural integrity and long-term reliability for enterprise environments requiring performance in reduced rack depth installations.

Despite its shorter 391mm depth, it maintains broad motherboard compatibility up to SSI-EEB, including SSI-CEB, Extended ATX, ATX, Micro-ATX and Mini-ITX. With eight expansion slots and support for expansion cards up to 361mm in length, it enables GPU-accelerated servers, edge computing nodes or virtualization platforms within a space-efficient 3U footprint.

The cooling system is optimized for rack airflow environments, featuring three 120mm front fans and dual 60mm rear exhaust fans. It supports front radiators up to 360mm while maintaining a 110mm CPU cooler clearance, ideal for low-profile high-performance air or liquid cooling configurations.

Designed for flexibility, it supports SFX and SFX-L power supplies, with adjustable PSU depth configuration depending on drive cage usage. Front USB Type-C connectivity, professional LED status indicators and a chassis intrusion switch complete this integration-ready solution for demanding IT infrastructures.
