3U Rackmount Chassis for MicroATX Boards

The Athena Power RM-3UWIN525 is a new 3U rackmount server chassis built from 1.2mm SECC steel in black. It accepts MicroATX, ATX and Mini-ITX motherboards and provides seven low-profile expansion slots for add-in cards.

Suits builds needing front PS2

This chassis fits administrators who want a front-mounted single PS2 or PS3 supply and four external 5.25in drive bays. It is not for installations that require full-height cards, hot-swap 3.5in trays or redundant power supplies.

Seven low-profile slots define card height

The single specification that decides fit is the seven low-profile expansion slots. Only half-height cards can be installed, so verify your add-in cards match that height before purchase.
