When talking about HTPC systems, you would probably be better off in a forum that is dedicated to HTPC. I am not a member of the following forum, but just thought I would give you a link. There are a few people here that have HTPC systems. But mostly we are gamers or just avid computer users.
I am not trying to chase you off, and please stick around, you can really be surprised at the knowledge on these forums.
