Compact 3U rackmount chassis

The iStarUSA D-300SEA-BL-HDD2535 is a 3U server rack with a blue aluminium front bezel and a black 1.2mm SECC zinc-coated steel chassis. It fits standard 19-inch racks and accepts ATX or microATX motherboards up to 12 by 9.6 inches. The unit includes a 2.5-inch to 3.5-inch drive converter for flexible storage.

Upgrade from tower or 2U cases

This chassis replaces tower servers or 2U racks when you need seven full-length expansion slots and room for four 5.25-inch bays plus three 3.5-inch drives. The jump is worth it when hot-swappable storage or RAID via optional BPU backplanes becomes a requirement. Builders who need more than seven slots or deeper motherboard support should look elsewhere.

Straightforward rack installation

Mounting uses standard 19-inch rails and the chassis depth of 20.80 inches fits many cabinets. A single 60mm fan is standard; adding three 80mm fans requires the DD-FANGUARD-8 bracket. Front USB 2.0 ports, power and reset switches, and a key lock are accessible behind the bezel. Temperature and fan indicators need the optional TC-ISF08 sensor board to function.

Questions about this item

Will the 19.00-inch wide chassis fit a standard 19-inch rack and what depth clearance does the 20.80-inch body need?

The chassis is exactly 19.00 inches wide for standard 19-inch racks and 20.80 inches deep, so allow at least that much clear depth behind the front mounting rails.

How do I install the optional three 80mm fans and the required DD-FANGUARD-8 bracket?

Mount the DD-FANGUARD-8 bracket into the designated fan area, then screw the three 80mm fans onto the bracket; the single standard 60mm fan fits directly into its rear slot without extra parts.

When should I replace the standard 60mm fan or add the optional 80mm fans for heavier thermal loads?

Replace the 60mm fan if airflow drops or noise rises; add the three 80mm fans with the DD-FANGUARD-8 bracket when component density or ambient temperature pushes the chassis beyond the single fan's capacity.
