4U Server Chassis with 8 Drive Bays

The Athena Power RM-4UWIN5258G is a 4U desktop server chassis designed for industrial and GPU compute workloads. It provides eight external 5.25-inch drive bays and two 3.5-inch bays alongside eight expansion slots. A front panel includes two USB 3.0 ports for quick peripheral access. The unit supports ATX motherboards and multiple power-supply form factors.

Upgrade from Tower or 2U Systems

This chassis replaces smaller tower or 2U enclosures when additional drive bays, full-length GPU clearance, or more expansion slots are required. The jump is worth it when a build needs eight 5.25-inch bays for optical drives or hot-swap cages and room for four graphics cards. Five included cooling fans manage airflow for dense configurations.

Suits Multi-GPU and High-Density Storage Builds

The design suits integrators building multi-GPU render nodes, deep-learning servers, or storage-heavy appliances that rely on 5.25-inch form-factor devices. Buyers needing a rackmount form factor, tool-less drive trays, or integrated redundant power supplies should look at alternative chassis models.

Questions about this item

What motherboard size fits the Athena Power RM-4UWIN5258G?

The chassis supports up to ATX motherboards, matching the 8 expansion slots provided.

How are the front USB 3.0 ports connected to the motherboard?

Route the internal USB 3.0 header cable from the front panel to a matching header on the board; the step often missed is securing the cable so it does not block airflow to the five cooling fans.

Which drive bays will need attention if a drive fails later?

The unit provides eight 5.25-inch and two 3.5-inch open bays; any failed drive in those bays can be swapped without removing the chassis cover.
