4U Ultra-Short Chassis for ATX Builds

This 4U server chassis measures 300 mm deep and accepts ATX motherboards up to 305 by 245 mm. It provides seven full-height expansion slots, two Phoenix ports and four COM ports for dense I/O configurations. The bare-bone frame is built from 1.0 mm Maanshan galvanised steel with a black sand spray finish. It ships with mounting hardware and a power cable for immediate assembly.

Thermals, Noise and Power

Two 6 cm rear fan positions are reserved for active cooling, allowing airflow across graphics cards and the motherboard. The open-frame layout and standard mounting holes keep cable routing tidy, which helps heat dissipation. An ATX power supply mounts in the standard location, and the front panel includes power and reset buttons with LED indicators. No acoustic or power-draw figures are supplied by the manufacturer.

Build Integration

The case supports two 3.5-inch or two 2.5-inch drives, but not both simultaneously, limiting storage density for users who need more bays. Seven full-height slots free up space for multiple add-in cards, while the 300 mm depth fits shallow racks or benches. Builders requiring additional drive bays, front USB 3.0 or a deeper chassis for longer cards will need a different enclosure.

Questions about this item

How do I install the ATX power supply in this 300 mm deep 4U chassis and which step do builders often miss?

Slide the ATX unit into the rear bay, align the four standard mounting holes, and secure all screws; the step most often missed is fastening the PSU before seating the motherboard, which blocks access to the rear screws.

What cooling maintenance will the two rear 6 cm fan positions require over time?

Remove the fan grilles every few months, blow dust from the blades and bearings with compressed air, and replace any fan that develops bearing noise or reduced airflow.

At what point does the 1.0 mm galvanised steel panel thickness limit sustained thermal performance?

The thin panels transmit heat quickly, so under continuous full-load mining the internal air temperature rises until the reserved 6 cm rear fans can no longer exhaust enough heat, making additional active cooling necessary.
