Claim 13:
14. An apparatus for cooling electronic circuitry, the apparatus comprising:
an enclosure configured to surround the electronic circuitry, the enclosure including a plurality of panels, wherein
a first one of the plurality of panels faces a first direction,
a plurality of air intake holes are disposed in the first one of the plurality of panels only in a portion thereof which provides a space for placement of at least one of a display or a connector in a lower portion thereof,
a second one of the plurality of panels faces a second direction that is opposite to that of the first direction, and
a plurality of air exhaust holes are disposed in the second one of the plurality of panels only in a portion thereof which provides a space for placement of at least one a connector in a lower portion thereof; and

an air plenum piece disposed within the enclosure and including
a substantially planar portion that extends from an inner wall of the first one of the plurality of panels and that ends at a distance from an inner wall of the second one of the plurality of panels, and
a plurality of tabs that extend from the substantially planar portion of the air plenum piece to an inner wall of an upper one of the plurality of panels, including
an end tab located at an edge of the substantially planar portion of the air plenum piece that is closest to the inner wall of the second one of the plurality of panels,
at least one side tab located at a side edge of the substantially planar portion of the air plenum piece, the side edge of the substantially planar portion of the air plenum piece being spaced apart from an inner wall of an adjacent side panel of the plurality of panels, and
at least another side tab located at another side edge of the substantially planar portion of the air plenum piece, the another side edge of the substantially planar portion of the air plenum piece being spaced apart from an inner wall of another side panel of the plurality of panels,
the at least another side tab extending only along a portion of the another side edge of the substantially planar portion of the air plenum piece, so that at least some of the air in the second volume is recirculated into the first volume,

the air plenum piece being configured to divide an interior region of the enclosure into a first volume into which the plurality of air intake holes open and a second volume into which the plurality of air exhaust holes open,
the first volume being enclosed by the inner wall of the first one of the plurality of panels, the substantially planar portion of the air plenum piece, the plurality of tabs, and the inner wall of the upper one of the plurality of panels,
the second volume being a remaining volume of the interior region,
the air plenum piece having an air plenum hole that forms an opening between the first volume and the second volume.
