Look for "Thermally Advantaged" cases. They are supposidly GREAT for cooling. They have air holes directly over the processor, and some have them right over the PCI slots. They often come with a tube, that gets placed from the side of the case (where the holes are) to millimeters above the processor. Thus bringing outside air in, and placing it directly over the processor. This was developed by Intel, primarily for their Prescott cores, but I would assume that it could be used for an AMD chip also.
