Compact 4U Rackmount Chassis

The iStarUSA D-400-6-SILVER is a 4U rackmount server chassis built from steel. It accepts motherboards up to 12" x 10" and provides six external 5.25" drive bays plus two external and two internal 3.5" drive bays. A single 80mm fan and a removable air filter handle airflow. Front-panel USB ports and standard LED indicators complete the package.

Build Integration Needs

This chassis fits a standard 19" rack and measures 19" x 7" x 20.8". Builders must supply their own power supply, cooling upgrades and cable routing hardware because none are included. The six 5.25" bays free up space for optical drives or hot-swap cages, while the four total 3.5" bays support a modest storage array. The 12" x 10" motherboard limit excludes larger server boards.

Included Extras

A removable air filter slides out for cleaning without tools, helping maintain positive pressure over time. The front panel includes a power LED, HDD activity LED, power switch and an alarm reset switch for quick fault acknowledgement. A standard I/O shield is provided to match the motherboard rear layout. No rails, screws or management software are bundled.

Questions about this item

How many internal 3.5" drive bays does the D-400-6-SILVER provide for storage expansion?

The chassis includes two internal 3.5" drive bays alongside two external 3.5" bays and six external 5.25" bays, giving multiple options for hard drives or removable media.

How loud is the single 80mm fan during continuous operation in a 4U rack?

Only one 80mm fan is fitted, so sustained loads will rely on that single unit for airflow; noise level will depend on the specific fan model installed and the thermal demand of the components inside.

What motherboard size fits the 12" x 10" compatibility spec of this chassis?

The case accepts boards up to 12 inches by 10 inches, which covers standard ATX and many micro-ATX server boards; verify your board's exact dimensions against that limit before purchase.
