Abstract

An apparatus casing (1) for a computer, which casing includes a number of walls which together define a chamber for accommodating computer components wherein at least a first wall (2) includes a number of through-penetrating contact openings (4, 9) which are disposed to enable the connection of external cables (6) having electric contacts (7) to corresponding connection contacts (5) disposed at said contact openings and connected to chamber-accommodating components. With the intention of lowering the airborne operational noise exiting from the box and counteracting the leakage of air into the casing, the casing is fitted with an openable canopy (11) that includes a generally hermetic wall (11') and an edge surface which, when the canopy is closed, lies against the outside of the first wall (2) around the contact opening (4, 9), and a sealing cable transit means (20) through which the cables (6) are able to extend, wherein the canopy (11) the cable transit means (20) and the first wall (2) form a space for accommodating the cable contacts (7) said space being delimited generally hermetically from the surrounding atmosphere outside the chamber. The invention also relates to a canopy (11) for such an apparatus box.
