3U rackmount chassis with internal 2.5 to 3.5

The iStarUSA D-300SEA-BK-HDD2535 is a 3U server rackmount chassis built for industrial and small-business deployments. It fits standard 19-inch racks and includes a front aluminium alloy bezel with a key lock. The chassis ships with a single 60 mm fan and accepts 1U or 2U power supplies. ATX and microATX motherboards up to 12 by 9.6 inches are supported.

Tool-free drive installation

Two external 3.5-inch bays, one internal 3.5-inch bay and four 5.25-inch bays provide flexible storage layout. An internal 2.5-inch to 3.5-inch converter is included for SSD mounting. Optional cooling adds one 60 mm and three 80 mm fans using the DD-FANGUARD-8 bracket. Seven full-length expansion slots accommodate add-in cards, while front-panel USB 2.0 ports simplify peripheral access.

Verify rack depth and motherboard clearance before

The unit measures 19.00 by 5.25 by 20.80 inches, so confirm your rack depth exceeds 20.80 inches with cable allowance. Ensure the chosen 1U or 2U power supply matches the chassis mounting pattern. Temperature and fan indicators require the optional TC-ISF08 sensor board. Buyers needing hot-swap backplanes or more than seven expansion slots should consider other form factors.

Questions about this item

How do I confirm the chassis is operating correctly after installation?

Verify the front-panel Power, HDD, Temperature and Fan LEDs are lit or blinking as expected; Temperature and Fan indicators require the optional TC-ISF08 sensor board to function.

What ships with the D-300SEA-BK-HDD2535 and what must be purchased separately?

The unit includes the 3U chassis with black aluminium front bezel, one standard 60 mm fan, 2.5" to 3.5" drive converter, front bezel key lock, two USB 2.0 ports and mounting hardware; optional extras are three 80 mm fans (require DD-FANGUARD-8 bracket), TC-ISF08 sensor board and BPU hot-swap backplanes.

Which drive-bay configuration should I choose for mixed 3.5" and 5.25" storage?

The chassis provides two external 3.5" bays, one internal 3.5" bay and four 5.25" bays; select this model when you need that exact mix without adding conversion kits.
