4U Rackmount Server Chassis

The iStarUSA D-406L-EC is a 4U rackmount server chassis built for Micro ATX and ATX motherboards. Its aluminum alloy construction keeps weight down while providing structural rigidity for dense deployments. The black finish suits standard data-centre aesthetics. This long-version chassis targets integrators who need extended internal clearance.

Cooling and Front I/O Limits

Three 120 mm fans and two 80 mm fans deliver airflow across the full depth of the enclosure. Liquid-cooling loops can be installed, but radiator length is bounded by the chassis interior. Front-panel I/O supplies two USB 3.0 ports for local media or diagnostic devices. No additional front-panel connectivity is provided.

Motherboard Form-Factor Gate

Micro ATX and ATX boards are the only supported form factors; E-ATX and larger server boards will not fit. Builders requiring dual-socket or extended-ATX layouts must select a different enclosure. The 4U height fits standard racks, yet the long depth may conflict with shallow cabinets. Verify rack depth before ordering.

Questions about this item

Should I choose the standard or the long version of this 4U rackmount chassis?

The D-406L-EC is the long version, giving extra depth for larger motherboards or additional drive cages compared with the standard model.

What does the 120 mm triple-fan layout mean for airflow in a populated server?

Three 120 mm fans at the front pull cool air across the motherboard and drive bays, while two 80 mm rear fans exhaust heat, providing balanced front-to-back cooling under load.

How does the front USB 3.0 interface perform when connected to a motherboard header?

Each front port runs at USB 3.0 speeds up to 5 Gb/s, limited only by the motherboard header and cable quality, so external SSDs or backup drives operate at their rated throughput.
