4U Rackmount Server Chassis

The iStarUSA D-400-6 is a 4U rackmount server chassis built from aluminum and steel with a black finish. It supports Micro ATX and ATX motherboards up to 12 by 9.6 inches. The unit provides six external 5.25 inch drive bays, two external 3.5 inch bays, and two internal 3.5 inch bays.

Suits High-Density Storage Builds

This chassis suits administrators who need many 5.25 inch bays in a compact 4U form factor for optical drives or hot-swap cages. Builders requiring more than seven expansion slots or native hot-swap backplanes without extra hardware should look at alternatives.

Seven Expansion Slots

The chassis offers seven expansion slots for add-in cards such as RAID controllers or network adapters. Cooling relies on one preinstalled 80mm fan with a mount for a second optional unit. Front-panel indicators show power, drive activity, temperature, and fan status when a sensor board is fitted.

Questions about this item

How much motherboard space does the 12" x 9.6" Micro ATX / ATX spec actually leave inside this 4U rackmount?

The chassis accepts boards up to 12" x 9.6", so standard ATX and Micro ATX fit with room for cables and full-length cards in the seven expansion slots.

What does the single pre-installed 80mm fan plus one optional 80mm slot cap in real-world airflow?

One 80mm fan ships installed; a second 80mm fan can be added for extra airflow, and a removable air filter sits in front of both positions.

Will the 7.00" height and 20.80" depth clear a standard 19" rack with rear cable management?

At 7.00" high (4U) and 20.80" deep, the unit fits a 19" rack; allow additional rear depth for cables and the seven-slot expansion area.
