The SilverStone RM47-502-I is a 4U rackmount server chassis designed for professional workstations, GPU computing systems, and server builds requiring convenient access to expansion cards.

Supporting SSI-EEB, SSI-CEB, E-ATX, ATX, Micro-ATX, and Mini-ITX motherboards, it provides a flexible foundation for professional computing systems.

Featuring 11 PCI expansion slots, including eight low-profile slots and three vertically oriented standard-height slots, the RM47-502-I accommodates a high-end consumer graphics card alongside additional expansion and adapter cards. Its steel chassis also supports rear-mounted radiators up to 280mm, includes one front 80mm cooling fan, and provides two external 5.25" device bays plus two internal 2.5" drive positions for versatile system configurations.

Overview

SilverStone RM47-502-I is a 4U rackmount chassis with 11 front-accessible expansion slots for one big graphics card plus many add-in cards. It takes SSI-EEB boards and fits a rear radiator up to 280mm. Local Singapore warranty support through Mansa.

Who it suits

  • If you run one high-end consumer GPU alongside NICs, HBAs or capture cards, you get 3 vertical standard-height slots plus 8 low-profile slots.
  • Front-facing expansion slots and I/O let you reach your cards without pulling the chassis out of the rack.
  • Liquid-cooled builds fit a rear radiator up to 280mm, or two 120mm, 140mm or 160mm fans.
  • Less suitable for multi-GPU configurations. SilverStone positions the RM47-502-I for one high-end consumer graphics card alongside multiple expansion cards, while the RM46-502-I supports up to four server-grade GPUs.

Before you buy

  • CPU cooler height drops to 114mm when a graphics card sits in the standard-height slots. It is 148mm with those slots empty.
  • Card width is 167mm for standard-height slots and 142mm for low-profile slots. Cards can be up to 437mm long without rear fans or a radiator.
  • PSU plus any 5.25" device must total 430mm or less. 2U Redundant PSUs need RM47-502-I V2.0 or later.

What is the difference between the RM47-502-I and RM46-502-I?

Both share the same 440 × 176 × 456mm external dimensions.

SilverStone lists the RMS05-22 slide rail as compatible. The spec sheet does not say rails are in the box, so treat them as separate unless we confirm otherwise.
