What's your price range? A "mid to high level" component system can range from a $2000 system to a $100,000 dollar system or even higher!!!

Also, how big is your room? Is it mainly for movies or music or both?? I'm guessing that since you mentioned a projector, it's a movie room. There are some Outlaws around here who have built some pretty sweet set-ups. They may have some ideas once you set your range.

Look forward to hearing some more info so we can spend your money!!
