1. An electronic equipment enclosure, comprising:
(a) a frame structure formed from a plurality of support posts and cross members, the frame structure having a front-to-back length and a side-to-side width;
(b) a top panel mounted on the frame structure, the top panel including:
(i) a plurality of outer edges, each outer edge of the plurality of outer edges partially defining a perimeter of the top panel, the perimeter having a front-to-back length and a side-to-side width, wherein each outer edge is generally perpendicular to two other outer edges of the plurality of outer edges,
(ii) a plurality of inner edges that define a rectangular opening in the top panel, the rectangular opening having a front-to-back length and a side-to-side width, wherein each inner edge of the plurality of inner edges is generally parallel to two outer edges of the plurality of outer edges, and
(iii) wherein the side-to-side width of the rectangular opening is at least 75% of the side-to-side width of the top panel perimeter;
(c) side panels and a back panel mounted on the frame structure and, together with the top panel, at least partially enclosing the frame structure and defining a single compartment for mounting an electronic component; and
(d) a collapsible exhaust air duct extending upward from the top panel, for exhausting hot air from the single compartment, the collapsible exhaust air duct comprising upper and lower sections nestingly arranged with one another and adapted to telescope in length, wherein:
(i) at least the lower section of the exhaust air duct is rectangular in cross- section that is defined by four panels having smooth interior surfaces and intersecting each other at right angles, the cross-section having a front-to- back length and a side-to-side width,
(ii) the front-to-back length of the exhaust air duct cross-section is substantially the same as the front-to-back length of the top panel rectangular opening,
(iii) the side-to-side width of the exhaust air duct cross-section is substantially the same as the side-to-side width of the top panel rectangular opening, and
(iv) the lower section of the exhaust air duct is disposed in surrounding relation to, and in fluid communication with, the top panel opening such that the four panels of the lower section of the exhaust air duct are directly aligned with the inner edges of the top panel and an interior of the exhaust air duct is in direct and unobstructed fluid communication with an interior of the single compartment.
