Compact 3U Rack Chassis

The iStarUSA DD-300-SEA-SILVER is a 3U rack mount chassis designed for compact server or workstation builds. It supports ATX and microATX motherboards up to 12 x 9.6 inches. The silver aluminium front bezel features a lock and two front USB 2.0 ports. A single 60 mm cooling fan is included.

Verify Motherboard And Drive Needs

Confirm your motherboard fits the 12 x 9.6 inch maximum size before ordering. The chassis provides four 5.25 inch external bays, two 3.5 inch drive bays and one internal 3.5 inch drive bay. Expansion is limited to seven full-length add-on card slots. Front USB headers on the motherboard are required for the two USB 2.0 ports.

Build Integration And Cooling Options

The 1.2 mm SECC steel chassis measures 20.80 deep x 19 wide x 5.25 high inches and includes power, HDD, temperature and fan status indicators plus power and alarm reset switches. An optional aluminium body reduces weight and improves thermal performance. Additional cooling can be added with one extra 60 mm fan or three 80 mm fans using the DD-FANGUARD-8 bracket.

Questions about this item

What comes in the box and do I need to buy a backplane or extra fans separately?

The chassis includes the aluminium front bezel with locks, two front USB 2.0 ports, one 60 mm cooling fan, power and HDD LEDs, plus power and alarm reset switches. An optional BPU backplane for hot-swap storage and the DD-FANGUARD-8 bracket for three additional 80 mm fans are sold separately.

Which version should I choose — the standard steel body or the optional aluminium chassis?

The standard unit uses 1.2 mm SECC zinc-coated steel throughout. The optional aluminium chassis reduces weight and improves thermal performance; select it if rack density and cooling headroom are priorities.

What does the 7 expansion-slot rating mean for a real build?

The backplane supports seven full-length add-in cards, and the motherboard tray accepts ATX or microATX boards up to 12 x 9.6 inches, so you can populate all slots with long GPUs or capture cards.
