4U Short-Depth Server

Model: 420S11T

Built with our most popular 4U chassis, the 420S11T is an excellent short depth server or workstation for projects that require full-sized expansion options. Despite its short 20" depth, this chassis can handle full-height and full-length expansion cards that require additional power connections. Ask us about additional serial and USB ports that can be provided in this system.
