Reasons I love business-grade laptops (macbooks, of course, excluded, if they could even be counted as business grade): I just finished taking my laptop apart, reapplying thermal paste to the cpu and gpu, and putting it back together. The hardest part of all this was when I had to run out to the store to buy some isopropanol. It was that simple. Dell even conveniently provides step by step instructions on how to get to the heatsink!
