Building the HT from the ground up already puts you at an advantage...many of us have to figure out a way to get our HTs to work in our existing non-ht environments...lets just say that can get just a little tricky
Hopefully you stay around and share you progress with us. It'll be fun to live vicariously through all of your experiences with awesome ht equipment!
And if you ever need help do let us know and I'm sure someone will have an answer for ya. Welcome aboard!
