Product Overview

2U Form Factor, Full-Size Possibilities

The SilverStone RM23-502 packs ATX compatibility into a 2U footprint, giving you server-grade density without restricting hardware choice. It supports ATX, Micro-ATX and Mini-ITX motherboards, standard ATX power supplies up to 180mm, and seven low-profile expansion slots—plenty of room for RAID cards, NICs or GPUs built for rack use.


Storage Capacity You Can Build Around

With dual external 5.25" bays, you’re free to deploy hot-swap cages, optical drives or front-access modules. Internally, it handles up to 5 x 3.5" HDDs and 1 x 2.5" SSD, delivering serious storage density for backup servers, NAS, or virtualisation nodes. No wasted space—just practical, flexible drive support.


Smart Cooling Layout for Server-Grade Airflow

A built-in fan bracket supports three 80mm x 38mm front fans, backed by an extra 60mm rear mount to maintain positive airflow. The 65mm CPU cooler height limit fits top-down coolers commonly used in 2U environments, keeping thermals under control even under sustained load.


Rack-Ready Convenience

The auto-lock front handle makes installation into a cabinet quick and secure. Sliding rail support is pre-drilled—just add the SilverStone RMS03-26 rail kit (sold separately) and you’re fully serviceable from the front. It’s built for real-world data centre workflows, not just spec sheets.


Connectivity and Control Up Front

Two USB 3.1 Gen 1 Type-A ports deliver 5Gbps performance (backwards compatible with USB 2.0/1.1) for rapid data access or configuration tools. Front panel buttons keep power and reset within easy reach, while dedicated LED indicators show system power, HDD activity and dual LAN status at a glance.

• Supports ATX power supplies of up to 180mm depth
• Supports 1 x 2.5" SSD and up to 5 x 3.5" HDD
• 5Gbps USB 3.1 Gen1 interface (downward compatible with USB 2.0 & USB 1.1)
