Built for 3U rack density

The Athena Power RM-3UWIN525P708 is a 3U rackmount server chassis designed for environments that need high storage density and flexible motherboard support in a standard rack. It accepts ATX, MicroATX and Mini-ITX boards, making it suitable for custom server builds, backup appliances or edge-computing nodes. The 1.2 mm SECC steel construction and included AP-P4ATX70FEP8 power supply provide a ready-to-deploy platform for system integrators and IT departments.

Motherboard clearance up to 12 x 9.6 in

The single specification that decides fit is the maximum motherboard footprint of 12 inches by 9.6 inches, which covers full-size ATX down to 6.7-inch Mini-ITX. Builders needing E-ATX or larger workstation boards cannot use this chassis, and any proprietary form factor outside the three listed standards will not mount.

Slide rails not included; verify rack depth

Installation is straightforward for experienced integrators: the 80 mm centre fans sit on an easy-install anti-vibration bracket, and the 60 mm rear fans are pre-positioned. Common issues are the absence of sliding rails in the box and the 17.13-inch chassis depth, which may exceed shallow racks or conflict with rear cable management arms.
