My home network is really my pride and joy. I have 8 machines total - 2 netbooks, 3 desktops, and 3 laptops. There is a 9th machine in storage, but I don't use it for anything and it largely just sits in the closet.
At the heart of the network are two machines - My HP DC7600 and my Compaq laptop. Unfortunately, Compaq (Hewlett Packard), through brilliance on their part, made rather poor design moves when building the Presario CQ62 series. These are a budget line of machines that price between $250-$500. And are comprised of Intel and AMD offerings.
My particular machine, Presario CQ62 220AU suffers from heating issues. This is because Compaq uses the same chassis with most of their CQ62 - Intel and AMD, simply putting the different motherboard into the same case. Unfortunately, this was a mistake on their part. The Intel offerings were pared with Intel GFX, which, quite frankly, run very cool. They are somewhat underpowered and most likely underclocked to improve battery life.
