Rackmount 4U chassis for ATX builds
The iStarUSA E-Storm E-4000 is a 4U rackmount server chassis built from steel and finished in black. It accepts standard ATX motherboards and includes a 400W power supply. The design targets system integrators and small-business IT teams who need a compact rack-mountable enclosure with room for legacy optical or hot-swap media.
Straightforward assembly with legacy bay constraints
Seven expansion slots align with ATX board layouts, and a single 120mm fan mounts at the rear for basic airflow. Three external 5.25in bays, one external 3.5in bay and one internal 3.5in bay provide storage flexibility, though cable routing can become tight when all seven slots are populated. Front-panel USB ports are present but limited to the single header provided.
Steady thermal profile under continuous operation
The lone 120mm exhaust fan moves air across the motherboard and drive cage during sustained workloads. With a 400W supply the chassis suits modest CPU and GPU configurations, but high-density or multi-GPU builds will exceed both the power budget and the single-fan cooling capacity. Dimensions of 19in x 17.8in x 7in fit standard 19in racks.

Questions sur cet article
How can I confirm the 400W power supply is delivering stable power after installation?
Check that the system posts, all drives spin up, and the 120mm fan runs steadily; a multimeter on the 24-pin and 4-pin connectors should read within ATX tolerance.
What ships with the chassis and which items must I source separately?
The steel 4U rackmount case, one 120mm fan, and the 400W power supply are included; motherboard, CPU, memory, drives and rails are not.
Which drive-bay layout should I choose for a build needing three 5.25" devices and one 3.5" drive?
This model provides exactly three external 5.25" bays, one external 3.5" bay and one internal 3.5" bay — no alternative configurations exist.
