Hi there, I'm looking to purchase my first plasma (Panny 42PH10) and an Onkyo 605. Also, I'm considering building an HTPC but have a couple of questions I'm comfortable building PC's but HDMI is new to me. Is it possible to output sound over an HDMI motherboard or gfx card to the amp? The HTPC won't be used for games so I'm looking at something like a E4400 CPU, is it possible for a low end C2D to be passively cooled? Thank you!
