4U Rackmount Server Chassis

The iStarUSA D-406-B6SA-SILVER-ND is a 4U steel rackmount chassis designed for server deployments requiring high-density storage. It accommodates motherboards up to 12" x 10" and provides seven expansion slots for add-in cards. The unit includes six hot-swap drive bays, two internal 3.5" bays, and two external 5.25" bays for versatile drive configurations. A single 80mm fan handles baseline airflow through the 20.8" deep enclosure.

Suited for storage-focused builds

This chassis fits administrators building file servers or backup appliances that benefit from front-access hot-swap trays. The six hot-swap bays simplify drive maintenance without shutting down the system. Builds relying on passive CPU coolers or high-wattage GPUs may find the single 80mm fan insufficient for thermal management. Systems needing more than seven expansion slots or front-panel USB 3.0 connectivity should evaluate alternative enclosures.

No bezels alter front access

The manufacturer highlights the absence of bezels, which leaves drive bay openings exposed for direct tray insertion or custom faceplate fabrication. This design choice removes the step of removing bezels during hot-swap operations but offers no dust filtering or aesthetic cover for unused bays. Two front USB 2.0 connectors provide legacy peripheral support for keyboards, mice, or boot media. No additional accessories or software bundles are included with the chassis.

Questions about this item

Does the chassis support standard ATX motherboards up to 12" x 10"?

Yes, the motherboard compatibility is listed as 12" x 10", which fits standard ATX boards within that footprint.

Can I keep using my existing 3.5" hard drives in the internal bays while using the hot-swap bays?

Yes, the chassis includes two internal 3.5" bays alongside the six hot-swap bays, so both drive types can operate simultaneously.

How can I verify the single 80mm fan is running after installation?

You can visually inspect the fan through the chassis vents or listen for its operation; the system BIOS will also report fan speed if the header is connected.
