Product information

Description

SilverStone RM31-MINI is a compact 3U rack-mount server case engineered in steel with a grey and black finish. The chassis accepts SFX and SFX-L power supplies and accommodates a wide range of motherboard form factors including EATX, ATX, Micro-ATX, Mini-ITX and SSI CEB. Storage options include two 3.5" bays and two 2.5" bays. Cooling provisions include a front 120 mm fan mount and a rear 60 mm fan mount, and the front I/O supplies two USB 3.2 Gen1 Type-A ports. The chassis dimensions are 438 × 391 × 132 mm, making it suitable for short-depth rack environments where space efficiency and compatibility are required.

Advantages

The RM31-MINI combines a small footprint with broad compatibility: support for SFX and SFX-L PSUs and multiple motherboard sizes provides installation flexibility. Its steel construction offers structural durability for rack deployments while the dual front USB 3.2 Gen1 Type-A ports enable fast external connectivity. Dedicated drive mounts for two 3.5" and two 2.5" drives allow mixed storage configurations without add-on brackets. The layout supports targeted airflow with a front 120 mm and rear 60 mm fan position for effective cooling in constrained rack spaces.

Suitable for

  • Compact rack servers in data closets and small server rooms
  • Home lab and SMB infrastructure where space is limited
  • Storage-focused builds combining 3.5" and 2.5" drives
  • Systems requiring SFX or SFX-L power supplies

Key specifications

  • Chassis type: 3U rack-mount server case, short-depth
  • Material: Steel with grey and black finish
  • Supported motherboards: EATX, ATX, Micro-ATX, Mini-ITX, SSI CEB
  • Drive bays: 2 × 3.5" + 2 × 2.5"
  • Power supply: accepts SFX and SFX-L form factors (not included)
  • Cooling: front 120 mm fan mount, rear 60 mm fan mount
  • Front I/O: 2 × USB 3.2 Gen1 Type-A
  • External dimensions: 438 × 391 × 132 mm

How to use

Install the appropriate motherboard into the chassis using the included standoffs and secure it with screws. Mount an SFX or SFX-L power supply in the PSU compartment and connect power cables to the motherboard and drives. Fit storage devices into the two 3.5" and two 2.5" bays using the provided mounting points, route cables to avoid obstructing airflow, and install fans in the front and rear positions as required. Connect external devices to the front USB 3.2 Gen1 Type-A ports. Slide the assembled chassis into a compatible 19" rack and fasten with appropriate rack screws.

Usage recommendations

For reliable thermal performance in rack environments, use a dedicated 120 mm front intake fan and ensure rear exhaust clearance. Choose a high-efficiency SFX or SFX-L power supply sized for the system load, and route cables along the chassis sides to maintain unobstructed airflow. When using high-power components on EATX or SSI CEB motherboards, verify connector clearance and PSU cable reach before final installation.
