3U rackmount server chassis for compact deployments

The Athena Power RM-3U300P608 is a 19-inch rackmount server case built to the 3U form factor. It accepts ATX, MicroATX and Mini-ITX motherboards and ships with a pre-installed 600W 80 PLUS Bronze power supply. The 15-inch depth keeps the footprint small for dense rack environments.

Three 5.25-inch bays and flexible 3.5/2.5-inch

Three external 5.25-inch drive bays sit at the front for optical media or hot-swap trays. Internally the chassis holds two 3.5-inch drives or three 2.5-inch drives in a hidden cage. Four full-height expansion slots support add-in cards such as RAID controllers or network adapters.

Washable air filter and three 80mm intake fans

A washable filter covers the front intake to reduce dust buildup inside the enclosure. Three 80mm ball-bearing fans pull cool air across the motherboard and drive cage. Front-panel indicators show power and drive activity, while two USB 2.0 ports give quick peripheral access.

Questions about this item

Will a MicroATX board with a full-height PCIe card fit behind the 3U front panel without hitting the 80 mm fans?

Yes — the chassis accepts MicroATX, ATX or Mini-ITX boards and provides four full-height expansion slots; the three 80 mm front fans sit in front of the motherboard tray, leaving the slot area clear.

After powering on, which front-panel LEDs confirm the 600 W 80 PLUS Bronze supply is delivering power and the drives are active?

The front panel shows a Power LED, an HDD activity LED and a Reset button; the Power LED lights when the PSU is on and the HDD LED flashes during drive access.

Does the box include rails for a 19-inch rack and are the three 5.25-inch bays ready for drives without extra caddies?

The chassis is a 19-inch rackmount unit with three external 5.25-inch bays; rails and any 5.25-to-3.5-inch adapters are not included and must be purchased separately.
