2U Micro-ATX Server Chassis

The Silverstone RM23-502-MINI is a 2U rackmount enclosure built for Micro-ATX boards measuring 9.6" x 9.6". It targets administrators deploying compact storage or application servers in standard racks. The chassis accepts ATX, 2U single or 2U redundant power supplies. Four low-profile PCI or PCIe slots provide room for add-in controllers or network cards.

Verify Motherboard and Drive Compatibility

Confirm your motherboard fits the 9.6" square Micro-ATX footprint before ordering. The internal drive cage holds one 2.5" SSD and up to two 3.5" HDDs; no other drive sizes are supported natively. Front dual 5.25" bays accept optical drives or hot-swap cages. Ensure any expansion cards are low-profile height to match the four rear slots.

Cooling and Power Characteristics

A built-in bracket accommodates up to two 80mm x 25mm fans for active airflow; fans are not included. With passive cooling only, thermals depend on component choice and rack airflow. The chassis supports ATX, 2U single or 2U redundant power supplies, letting you match power capacity and redundancy to the installed hardware load.

Questions about this item

What comes inside the RM23-502-MINI box and what must I purchase separately?

The chassis includes a fan bracket for two 80mm fans and mounts for one 2.5" SSD plus two 3.5" HDDs. You must buy the power supply, motherboard, drives, fans and any 5.25" devices separately.

Should I choose a single or redundant 2U power supply for this 2U rackmount case?

Both ATX (PS2) single and 2U redundant power supplies fit. Pick redundant if uptime is critical; a single unit is simpler and cheaper for less demanding workloads.

How does the 5Gbps USB 3.1 Gen1 port perform when connected to a real motherboard header?

The front-panel port delivers up to 5Gbps and is backward compatible with USB 2.0 and 1.1 headers, so actual speed depends on the motherboard header you plug it into.
