4U Rackmount Chassis for Compact Server Builds

The iStarUSA D-400SEA-BK-HDD2535 is a 4U rackmount cabinet designed for ATX or microATX motherboards. Its black aluminium front bezel and 1.2mm zinc-coated steel chassis provide a sturdy industrial enclosure. The unit includes a built-in 2.5 to 3.5 inch drive converter for flexible storage options.

Standard Cooling and Expansion Layout

A standard 80mm and 120mm fan deliver airflow, with an optional 80mm mount available for additional cooling. Seven expansion slots support add-in cards such as RAID controllers or network adapters. Front-panel indicators show power, drive activity, temperature and fan status when a sensor board is fitted.

Upgrade from Tower or Smaller Rack Cases

This chassis replaces tower enclosures when equipment must mount in a standard 19 inch rack. It suits builders who need up to seven expansion cards and a mix of 5.25, 3.5 and 2.5 inch bays. It does not serve users requiring hot-swap backplanes, redundant power supplies or deeper cabinets for extended-length cards.
