Patent ID: 7768781

Claim:
A personal computer comprising: a central air plenum straddled by opposed first and second drive bays; at least one memory module disposed in the plenum; and a shroud covering the memory module and configured to establish an air flow over the memory module that is greater than an air flow over the memory module otherwise would be without the shroud; the shroud including a front flat surface closely spaced from the memory module and oriented substantially horizontally when the computer is oriented upright, the first flat surface terminating at a rear edge thereof in an upwardly-ramping surface, the upwardly-ramping surface in turn terminating at a rear edge thereof in a rear horizontal surface that is closely juxtaposed with a middle of a central plenum fan so that the fan moves air below the front flat surface of the shroud over the memory module and also moves air above the shroud to cool components above the shroud.
