The unpunched holes are actually punched. The blocked holes are blocked by the construction of the "screwless" xbox. They used the vent holes to snap some parts of the xbox together. So Microsoft inteded on those holes being blocked so that is not the problem. In fact, someone allready said that if you suspend the Power Supply and let the heat disperse from all sides of it, that it actually cures most of the heating problems. Like hanging it in mid air from a string or something.
