So we're all set on our hardware since we added more RAM, a video card and an HDTV tuner. I guess it's time to boot this puppy up and hope it works! Remember that our goal was to take a base Windows Media Center PC and add a few components to it for high-definition viewing for under $1,000. The total bill so far is $947, so we're good there. What else could go wrong now that we're in the home-stretch?
