If you are going to be doing a lot of video converting and such over night, I would probably suggest getting a laptop stand of your choosing. Lots of us here have mStands or Griffin Elevators, so you can take a look at those. Some people might say that it doesn't really help, but from my experience converting stuff over night on my macbook connected to my Dell monitor, it reduced the temp by at least 5 degrees Celsius. And it makes it a lot easier to look at when it is next to your ACD.
Hope that helps
