3U Rackmount Server Chassis

The Athena Power RM-3U3046X708 is a 3U rackmount server chassis finished in black and supplied with a 700W power supply. It accepts ATX, E-ATX and Micro ATX motherboards, making it suitable for compact server builds or workstation deployments in standard racks. The unit measures 21.65" x 19" x 5.25" and weighs 30lbs.

Four 5.25" Bays and Six 3.5" Slots

This chassis replaces older enclosures that lack front-accessible 5.25" bays or sufficient internal 3.5" drive positions. Four external 5.25" bays support optical drives or hot-swap cages, while six internal 3.5" bays provide dense storage capacity. The jump is worth it when a project needs both media access and multi-drive arrays in a single 3U space.

Included 700W PSU and Dual 80mm Fans

A 700W PS2 power supply (model AP-P4ATX70FEP8) is pre-installed with ATX 24-pin, EPS 8-pin, PCIe 6-pin and 6+2-pin, SATA 15-pin and Molex 4-pin connectors. Cooling relies on one 80mm front intake fan with an air filter and one 80mm rear exhaust fan. Installers should verify that the fixed fan layout matches component thermal limits before finalising the build.

Questions about this item

How deep is the rack required to be for the 21.65" chassis depth?

The chassis is 21.65 inches deep, so the rack must provide at least that much usable depth plus cable clearance at the rear.

Which motherboard power connectors does the included 700W PSU provide for an E-ATX board?

The AP-P4ATX70FEP8 supply includes a 24-pin ATX, an 8-pin EPS 12V, and a 4-pin P4-12V connector for E-ATX power.

How often should the front 80mm intake fan's air filter be cleaned?

Clean the front panel air filter every three to six months, or whenever visible dust builds up, to maintain airflow to the six internal 3.5" drive bays.
