Compact 1U rackmount server chassis

The Athena Power RM-1UC138 is a 1U rackmount server chassis built from 1.0mm SECC steel in a black finish. It accepts Mini-ITX motherboards measuring 6.7 in. by 6.7 in. and is aimed at administrators deploying space-constrained servers or network appliances in standard 19-inch racks.

Build integration and freedoms

A FlexATX power supply must be sourced separately and slides into the dedicated bay. Two front-mounted 40mm fans pull air through a removable, washable filter, cooling up to two 3.5-inch or 2.5-inch internal drives. One external 5.25-inch bay and a front USB 2.0 header remain accessible for media or peripheral needs.

Upgrade path and limits

The unit replaces older, deeper rackmount cases that waste rack depth and lack tool-less drive access. It is not suited for builds requiring full-size ATX boards, multiple expansion slots or liquid-cooling clearances, so buyers needing those capabilities should look elsewhere.

Questions about this item

How many 40 mm fans cool the chassis?

Two front-mounted 40 mm fans provide airflow through the 1U enclosure.

What noise level should I expect from the dual 40 mm fans under continuous load?

Small 40 mm fans typically spin faster than larger units, so sustained operation produces noticeable high-pitched airflow noise in a quiet room.

Which power supply must I supply because it is not included?

A FlexATX single power supply is required to power the Mini-ITX board and internal drives.
