3U Rackmount Chassis with Red Aluminium Bezel

The iStarUSA D-300SEA-RD-RAIL24 is a 3U rack-mount cabinet built from 1.2 mm SECC zinc-coated steel with a patented aluminium front panel in red. It includes a 20-inch sliding rail kit for quick installation in standard 19-inch racks. A single 60 mm fan provides standard airflow, while front-panel LEDs show power and drive activity.

Suited for ATX or microATX builds needing front

This chassis fits motherboards up to 12 by 9.6 inches and accepts 1U or 2U power supplies. Seven expansion slots support full-height cards. It is not for builders who need more than three 3.5-inch drive positions or who require 80 mm fans without purchasing the separate DD-FANGUARD-8 bracket.

20-inch sliding rails and dual front USB 2.0 ports

The bundled rail kit lets the unit slide clear of the rack for maintenance without tools. Two front-access USB 2.0 ports give immediate connectivity for peripherals or boot media. The key-locked bezel secures the four 5.25-inch and two external 3.5-inch bays, while an internal 3.5-inch bay remains available.
