Compact 4U rackmount chassis for small-server builds

The iStarUSA D-400SEA-BK-T7SA is a 4U rack-mount cabinet designed for ATX and microATX motherboards up to 12 by 9.6 inches. It suits builders assembling a single-server node in a standard 19-inch rack where space and budget are tight.

Drive and cooling limits defined by the 4U form

The chassis accepts four 5.25-inch bays, one external 3.5-inch bay and two internal 3.5-inch drives. Standard cooling uses one 120 mm and one 80 mm fan with an optional second 80 mm fan; temperature and fan-speed indicators require the separate TC-ISF08 sensor board.

Straightforward rack install but watch drive-cage

The unit slides into a 19-inch rack using the included handles and locks via the front bezel key lock. PS2 or mini-redundant power supplies fit the rear opening. Adding the optional BPU-230 hot-swap cage reduces internal 3.5-inch capacity, so plan the drive layout before final assembly.

Questions about this item

Should I pick the standard cooling or add the optional 80 mm fan?

Standard cooling already includes one 120 mm and one 80 mm fan; the optional 80 mm fan adds a third unit for extra airflow if your components run hot.

What does the 4U height mean once the chassis is mounted in a rack?

It occupies four rack units, giving 7.00 inches of vertical space for an ATX or microATX motherboard, power supply, and up to seven expansion cards.

Which drive interface does the hot-swap cage support and what speed does it cap at?

The BPU-230 cage handles SATA and SAS drives at up to 6 Gbps per port.
