1U Rackmount Server Chassis

The Athena Power RM-1U100DD308 is a 1U rackmount server chassis built for Mini-ITX motherboards measuring 6.7 by 6.7 inches. It includes a 300W FLEX ATX power supply with 80PLUS Bronze efficiency and fits a standard 19-inch rack. This unit suits integrators deploying compact servers or network appliances in data-centre racks.

Installation and Common Issues

The chassis uses an aluminum front panel and 1.2mm steel construction with four front 40mm intake fans and four side 40mm exhaust fans pre-installed. A washable air filter covers the front intake. Builders must route cables carefully in the 15.25-inch depth; the dense 40mm fan array can be loud under load and leaves little room for tall CPU coolers or full-height expansion cards.

FLEX ATX Power and 1U Constraints

The included 300W FLEX ATX supply limits total system power to 300 watts at 80PLUS Bronze efficiency, so high-TDP processors or multiple drives may exceed the budget. Only two USB 2.0 ports are available on the front panel. The 1U height restricts cooler height and prevents standard ATX power supplies, making component selection critical for thermal and electrical headroom.

Questions about this item

How do I confirm the 300W FLEX ATX power supply is delivering stable power after installation?

The front panel LEDs for power and hard-drive activity will light up, and the eight 40mm fans — four intake at the front and four exhaust at the side — should spin audibly when the system is running.

Which components come in the box and which must be sourced separately?

The chassis includes the aluminum front panel, 1.2mm steel body, eight pre-installed 40mm fans, washable air filter, 300W 80PLUS Bronze FLEX ATX supply (model AP-MFATX30P8), power and reset switches, and two front USB 2.0 ports. A Mini-ITX motherboard, CPU, memory, and storage are not included.

The model number ends in 308 — does that indicate a different capacity or feature set I should choose over other versions?

RM-1U100DD308 is the single SKU for this 1U rackmount case with the 300W Bronze supply and eight 40mm fans; no alternate capacity or feature variants are listed under this model.
