I'm still doubting the performance of a fanless Heatsink, the idea seems pretty dangerous to me, unless you live in a place that is constantly below 20 degrees celcius, I can imagine the heat that the CPU will generate after about 3 hours of constant use, like if you were watching a Movie or something. Most normal media center cases allow to 80mm to be fitted on, you fit a watercool heatsink pretty easily on one, like I said a couple post back.
