I just got to say my project based on this board is just about complete.
Sound, video,etc, yea it is all good, but what is key to this board is that it enable me to do everything I wanted stuffed into a mATX case.
No more need for separate components such as Amp, Blu-ray player, PC, Radio, PVR/extender, etc.
So now instead of some big home theater system with cables going everywhere, and needing to control multiple devices, I have one case connected to my plasma and speakers with all cables going behind the wall. My HTPC is sitting on a lower shelf of a small sofa table, it really opened up the room.
Before I would always use the TVs sound except for DVDs or Blu-ray movies, now I just leave the output going to the external speakers because it is easier and the sound is good regardless if at low or high volume.
To me, it just made the HTPC much more convenient and a clean look.
