We're about to start the remodel of the living room which includes walling off a useless triple glass door which will now be the wall for the tv and speakers. Once we get everything done and I start putting the stuff together, I'll post up what I've done. The HTPC might be a little bit down the road, but definately done in the next couple of months.
Between the construction and the new TV and speakers and other equipment, we're looking at about 25K already... and that's before the wife starts her room wish list, so the HTPC will be last on the list but I think it'll actually be one of the most valuable additions assuming it works the way I'm hoping it does.
