SilverStone SST-RM31 Rack 3U

The SilverStone SST-RM31 is a professional 3U rackmount server chassis engineered for high-performance infrastructures requiring powerful hardware integration and exceptional expandability. Its solid steel construction and enterprise-class layout make it ideal for data centers, GPU servers, AI computing nodes and high-density storage systems.

This chassis supports a wide range of motherboard formats including SSI-EEB, SSI-CEB, Extended ATX, ATX, Micro-ATX and Mini-ITX, providing maximum flexibility when building professional server platforms. With eight full-height PCI expansion slots, it enables the installation of multiple GPUs, accelerator cards, RAID controllers or high-speed network adapters.

The SST-RM31 is designed for demanding workloads and GPU-accelerated servers. It supports expansion cards up to 458 mm in length and offers an efficient cooling system with three 120 mm front fans and two 60 mm rear fans. Additionally, the chassis supports liquid cooling radiators up to 360 mm, enabling high-performance thermal management for compute-intensive environments.

For mission-critical deployments, the chassis supports dual power supply configurations. The primary PSU slot supports SFX, SFX-L or redundant 2U CRPS power supplies, while a secondary PSU slot allows the installation of an additional SFX or SFX-L power supply (after removing the 3.5" drive cage). This design improves power redundancy and reliability in professional rack infrastructures.
