Compact 4U Rackmount Chassis
The iStarUSA D-406-EC is a 4U aluminium-alloy server chassis built for standard-depth racks. It accepts Micro ATX and ATX motherboards, making it suitable for compact server builds and edge deployments. The 19.00" x 7.00" x 20.80" frame fits typical cabinet spacing.
Front USB 3.0 And Dual 80mm Fans
Two front-access USB 3.0 ports provide direct peripheral connectivity without reaching the rear panel. Twin 80mm cooling fans deliver baseline airflow for installed components. Power and HDD LEDs give immediate status visibility at a glance.
Standard Depth Limits Expansion Length
The standard-depth interior restricts the maximum length of add-in cards and storage cages compared to deep-chassis alternatives. Builders needing extra-long GPUs or high-density drive arrays must verify clearance before assembly. Liquid-cooling readiness helps thermal headroom within the fixed volume.

Questions about this item
Are the front USB 3.0 ports replaceable if they fail?
The chassis includes two front-access USB 3.0 ports; replacement would require sourcing a compatible panel module from the manufacturer.
What is the first thermal limit reached under sustained load with the two 80 mm fans?
The dual 80 mm fans provide the only active airflow; sustained loads are limited by the air volume these fans can move through the 20.80" deep enclosure.
How much noise and heat do the two 80 mm fans produce when the system runs all day?
Two 80 mm fans spinning continuously generate a moderate noise floor and exhaust warm air from the 20.80" deep chassis; exact decibel and temperature figures depend on the installed components.
