Excellent - I’ve been waiting for you to blog about this since you mentioned you were building a P-M HTPC a few weeks ago. I will get round to building a very similar machine in a couple of months time - thanks very much for the insight on quiet components etc.
Out of interest, do you have any performance issues with it yet? I was thinking of building a very similar specced machine to yours, but a friend of mine recently put together a Media Center PC and spent in excess of 800 (approx $1500) on it - he had a really high-spec machine. Do you really need a kick-ass machine to decode DVDs and record tv?
