Over the years as a PC hardware enthusiast I've come to trust AnandTech for the technical write ups about FSB overclocking, cooling, and etc.. But I stumbled upon this article and thought it was a good read. http://www.anandtech.com/mac/showdoc.aspx?i=3203&p=2 Most notably: This explains why there is so many posts and threads about how unsuitable the product is. And this I think is a good reason how the situation arose. Notice this is page two of their article. There is also a page one that centers around the hardware side regarding the processor.
