Much of the early design work at Cisco was done by the same person who did a lot of the design work on the KL-10 (which became the DECSYSTEM-20). A representative of DEC was asked the same question about the KL-10 at a meeting of DECUS (the DEC Users' Society): Why is the KL-10 so noisy? His response was: "You're got to realize that the KL-10 cabinet was originally designed as a hovercraft." I believe the AGS+ continues the same technology: It was intended for use in situations where it is not practical to use a rack -- just face the fans down and let it hang in the air.
