As shown in FIG. 1 , the unit 12 includes a vertical front panel 21 which includes a window 22 to enclose the computer components within the frame 18. The window 22 permits visual inspection of the components mounted within the unit 12.

With reference to FIGS. 1 , 5 and 6, the airflow path through the system 10 will now be considered. The air flow path is generally in the vertical direction past the generally vertically mounted computer components such as the computer component 16. In one form of the invention as disclosed herein, and as indicated by the arrows in FIG. 1 , the air enters horizontally at the bottom front of the system 10 and then travels vertically upwardly through the units 12 and 14 and exits at the upper rear portion on the system 10. A bottom fan and plenum unit 23 draws air horizontally into the system 10 and then directs it upwardly through the system 10. An intermediate fan unit 25 (FIG. 1 ) is disposed between the component units 12 and 14 to facilitate the upwardly directed vertical airflow path to a top fan and plenum unit 27. From there, the air exhausts horizontally to the rear of the system 10.

Considering now the fan and plenum bottom unit 23 in greater detail as best viewed in FIGS. 8 and 9, the bottom unit 23 includes a reversible plenum 29. Air is drawn into the plenum 29 through a perforated front plate 30 (FIG. 1 ), into an opening or mouth 31 of the plenum 29. As hereinafter described in greater detail, the plenum 29 is reversible and can be positioned such that the opening or mouth 31 is facing to the rear of the bottom unit 23 so that air can be drawn into the system 10 from the rear thereof as an alternative path of travel for the air.

The bottom unit 23 includes a fan compartment 32 mounted above the plenum 29 and includes a group of fans such as a fan 34 positioned to exhaust air from the plenum 29 and direct it upwardly into the bottom of the unit 14.
