Compact 3U rackmount chassis

The iStarUSA D-300SEA-BK-T7SA is a 3U rackmount cabinet built for standard 19-inch racks. Its front bezel uses patented aluminum alloy with a key lock, while the main chassis is 1.2mm SECC zinc-coated steel from Japan. A single 60mm fan provides standard cooling and front USB 2.0 ports allow quick peripheral access.

Suits ATX or microATX builds with legacy bays

This chassis fits motherboards up to 12 by 9.6 inches and accepts both 1U and 2U power supplies. Seven expansion slots support full-length cards. Builders who need hot-swap SATA or SAS trays at 6 Gbps can add the optional rugged 5.25-to-3.5 conversion rack. Systems requiring more than two external 3.5-inch bays or four 5.25-inch bays should consider a larger enclosure.

Seven expansion slots define card capacity

The fixed count of seven slots determines how many add-in cards the system can host. Verify that your GPU, RAID controller and networking adapters fit within this limit before purchase.

Questions about this item

How do I install the 3U chassis into a standard rack, and which step is often missed?

Mount the unit using the front bezel screw holes in a 19.00-inch rack; the step often missed is fitting the DD-FANGUARD-8 bracket before adding the three optional 80mm fans.

What maintenance or replacement will the cooling system need later?

The standard 60mm fan can be swapped out directly; the three optional 80mm fans require the DD-FANGUARD-8 bracket to be removed first.

What limit appears first during sustained operation?

The single standard 60mm fan provides the baseline airflow; without the optional three 80mm fans and DD-FANGUARD-8 bracket, thermal headroom is reached sooner.
