4U rackmount server chassis

The iStarUSA D-400 is a 4U rackmount chassis built from 1.2mm SECC zinc-coated steel with an aluminum alloy front bezel. It accepts ATX and microATX motherboards up to 12 x 9.6 inches and provides seven expansion slots for add-in cards. A key-locked front bezel secures the drive bays and controls.

Four 5.25-inch and three 3.5-inch drive bays

Four external 5.25-inch bays, one external 3.5-inch bay and two internal 3.5-inch bays support up to five drives for RAID configurations. Front-access dual USB 2.0 ports simplify peripheral connection. One 120mm fan and one 80mm fan work with a removable air filter to manage airflow.

Suits compact rack builds needing front USB

This chassis fits users who want a short-depth 4U enclosure with front-panel USB 2.0 and a locking bezel for physical security. Builders requiring hot-swap backplanes, tool-less drive trays or deeper component clearance should evaluate other platforms.

Questions about this item

What maintenance does the removable air filter need?

The removable air filter can be taken out and cleaned to keep airflow clear for the 80 mm and 120 mm fans.

Which limit appears first when the chassis runs under sustained load?

Cooling capacity is set by one 80 mm fan and one 120 mm fan, so thermal headroom is the first constraint during continuous operation.

How much noise and heat do the 80 mm and 120 mm fans produce all day?

One 80 mm and one 120 mm fan provide the only active cooling; acoustic output and exhaust temperature will reflect that dual-fan configuration.
