## Long description

The SILVERSTONE SST-RM31 is a rack-mount server case designed for compact rack systems and server deployments. With dimensions of 438×488×132 mm and a grey/black steel construction, this chassis accepts SFX and SFX-L power supplies and supports motherboard form factors from Mini-ITX up to EATX and SSI EEB. The RM31 provides two 3.5" and two 2.5" drive bays, front provision for 120 mm fan mounting and a rear 60 mm fan location, plus two front USB 3.2 Gen1 (Type-A) ports for fast external connectivity.
Advantages
The RM31 combines a compact 1U/2U-style rack footprint with broad motherboard compatibility, enabling dense server builds in limited rack space. Steel construction ensures structural rigidity for server workloads while support for both SFX and SFX-L power supplies allows flexible PSU choices. Integrated front USB 3.2 Gen1 ports and multiple internal drive bays simplify connectivity and storage expansion without increasing chassis size.
Suitable for
Small rack servers and compact rack-mounted workstations
High-density storage or compute nodes with mixed 3.5" and 2.5" drives

How to use
Install the chosen compatible motherboard and mount SFX or SFX-L power supply according to the chassis mounting points.

Connect front-panel USB ports to the motherboard headers. Slide the assembled chassis into a compatible rack space and fasten with rack-mount hardware appropriate to your rack rails.
Usage recommendations
For stable operation in rack environments, verify clearance and rail compatibility before installation, select quality SFX or SFX-L power supplies that meet your system power requirements, and plan airflow by using the front fan positions and rear fan location to establish front-to-back cooling. Use appropriate anti-vibration mounting for hard drives and secure cabling to maintain airflow and serviceability.
