Compact 3U rackmount chassis

The iStarUSA D-300SEA-RD-T7SA is a 3U server rack cabinet with a red aluminium front bezel and black 1.2mm SECC zinc-coated steel chassis. It supports ATX and microATX motherboards up to 12 by 9.6 inches and accepts 1U or 2U power supplies. A single 60mm fan is fitted as standard.

Suits space-constrained rack builds

This unit fits builders who need up to four 5.25-inch bays, two external 3.5-inch bays and one internal 3.5-inch bay in a shallow 20.80-inch depth. Front-panel USB 2.0 ports, power and HDD LEDs, plus power and alarm reset switches are included. Buyers who require more than seven expansion slots or hot-swap drive carriers without adding optional hardware should look elsewhere.

Seven expansion slots define capacity

The chassis provides exactly seven low-profile expansion slots, limiting add-in cards to that number. Optional cooling upgrades to one 60mm and three 80mm fans require the DD-FANGUARD-8 bracket. Temperature and fan indicators need the separate TC-ISF08 sensor board to function.
