3U Rackmount Chassis with Four 5.25" Bays

The iStarUSA D-300SEA is a 3U rackmount server chassis designed for compact deployments that still require multiple front-accessible drives. It accepts ATX and microATX motherboards up to 12 x 9.6 inches, making it suitable for general-purpose server builds and industrial applications where space is limited.

Single 60mm Fan with Sensor Indicators

Cooling is handled by one 60mm fan, while front-panel LEDs show power, drive activity, temperature and fan status when the optional TC-ISF08 sensor board is installed. The chassis supports 1U or 2U power supplies, allowing builders to match power capacity to their specific component load without prescribing a fixed wattage.

Aluminium and Steel Build with Lockable Bezel

The body combines aluminium and steel, and the front bezel features a key lock to restrict physical access to the drive bays and controls. Seven expansion slots accommodate full-length add-in cards, while two USB 2.0 ports on the front provide convenient peripheral connectivity for maintenance or temporary devices.

Questions about this item

How do I mount the D-300SEA in a 19-inch rack, and which step is often missed?

The chassis is 19.00 inches wide and 3U high; the step often missed is installing the optional sensor board TC-ISF08 so the front temperature and fan indicators actually work.

What will need replacement first on the D-300SEA?

The single 60mm fan is the only moving part; it should be checked regularly and swapped when airflow drops or noise rises.

What thermal limit appears first under sustained load in the D-300SEA?

With only one 60mm fan, the internal air temperature hits its ceiling before the seven expansion slots or four 5.25-inch bays fill up.
