3U Compact Rackmount Chassis

The iStarUSA D-300SEA-SL-T7SA is a 3U server rack built from 1.2mm SECC zinc-coated steel with an aluminum alloy front bezel in silver. It fits standard 19-inch racks and accepts ATX or microATX motherboards up to 12 by 9.6 inches. The unit suits small businesses or remote offices needing a short-depth enclosure for up to seven expansion cards.

Sustained Thermal Behaviour

A single 60mm fan ships as standard cooling for continuous airflow through the chassis. Optional upgrades add one more 60mm fan and three 80mm fans when the DD-FANGUARD-8 bracket is fitted, improving heat dissipation under prolonged load. Front-panel LEDs show power, drive activity, temperature and fan status when the TC-ISF08 sensor board is installed.

Installation Practicalities

The chassis supports 1U or 2U power supplies and provides two external 3.5-inch bays, one internal 3.5-inch bay and four 5.25-inch bays for drives or hot-swap cages. Front USB 2.0 ports and a key lock on the bezel aid daily access. Builders needing more than seven slots or deeper motherboards should choose a larger enclosure.
