SKU CH-4066-2M8X3

A 2U rackmount chassis for Micro-ATX boards with dual 5.25-inch bays and low-profile expansion slots

  • Product typeServer
  • Supports Micro-ATX boards up to 9.6" x 9.6
  • Dual 5.25" bays for optical drives or accessories
  • Holds one 2.5" SSD and two 3.5" HDDs
  • Four low-profile PCI or PCIe expansion slots
  • Two 80mm fan mounts for active airflow

2U Micro-ATX rack server for dense deployments

The SilverStone RM23-502-MINI fits a Micro-ATX board up to 9.6" x 9.6" in a 2U rack profile. It accepts ATX or redundant power supplies and provides four low-profile PCI or PCIe slots. The chassis suits builders who need a compact, rack-mountable platform for storage or compute nodes.

Air cooling with dual 80 mm fan support

A built-in bracket holds up to two 80 x 25 mm fans to move air across the motherboard and drives. The design relies on standard air cooling without liquid loops. Acoustic output and power draw will depend on the chosen fans, power supply and installed components rather than the chassis itself.

Dual 5.25" bays and front USB 3.1 Gen1

Two 5.25" drive bays allow optical drives, hot-swap cages or other accessories. Internal mounts take one 2.5" SSD and up to two 3.5" HDDs. A single front USB 3.1 Gen1 port runs at 5 Gbps and remains compatible with USB 2.0 and 1.1 devices. No software or extra cables are bundled.

Questions about this item

How do I install the motherboard and which step is often missed?

Mount the Micro-ATX board on the 9.6" x 9.6" standoff pattern and secure the I/O shield before sliding the chassis into the rack; the shield is frequently forgotten.

What maintenance will the cooling need later?

The built-in bracket holds two 80mm x 25mm fans; clean dust from the blades and replace any fan that becomes noisy or stops spinning.

What limit appears first during sustained load?

Only four low-profile PCI or PCIe slots are available, so expansion card capacity is reached before thermal or drive-bay limits.
