3U Rackmount Chassis with Drive Converter

The iStarUSA D-300SEA-SL-HDD2535 is a 3U rackmount cabinet built from 1.2mm zinc-coated steel with an aluminium front bezel. It accepts ATX and microATX boards up to 12 by 9.6 inches and includes a 2.5 to 3.5 inch drive converter. System builders needing a compact industrial enclosure with front USB 2.0 ports will find the layout practical.

2.5 to 3.5 Inch Internal Drive Converter

The chassis ships with a converter that lets a single 2.5 inch SSD or HDD mount in a 3.5 inch internal bay. Without this part a 2.5 inch drive cannot be secured in the standard drive cage. Buyers who plan to run only 3.5 inch mechanical drives or who need multiple 2.5 inch bays should note the converter covers just one position.

Front Bezel Lock and Optional Fan Bracket

A key lock on the silver bezel secures the front door and drive bays against casual access. Cooling starts with one 60 mm fan; adding three 80 mm units requires the separate DD-FANGUARD-8 bracket. Temperature and fan LEDs on the front panel only function when the optional TC-ISF08 sensor board is installed.

Questions about this item

What does the 3U height mean for fitting this chassis into a standard rack?

It occupies three rack units (5.25 inches) of vertical space, leaving room above or below for other equipment in a 19-inch cabinet.

Which power supply form factors does the chassis accept?

The chassis supports both 1U and 2U redundant or single power supplies, giving flexibility for different power budgets.

What are the exact outer dimensions needed to plan rack depth clearance?

The unit measures 19.00 inches wide, 5.25 inches high and 20.80 inches deep, so allow at least 20.80 inches of usable rack depth.
