A quick note on your optical Blu-ray drivers. In my experience LG has been far better than Sony ones, and many people agree. In fact I think LG has been making the best ones.
I'm too lazy to read all of it to offer more criticism other than the fact that when it comes to power making a PC as powerful as an HD console is more or less the same price, not "significantly" as you put it. For a PC to be significantly costlier it would be significantly more powerful than either HD console too.
Esit: Seagate HDDs have recently started to be the worst possible HDDs with a higher failure rate, also Western Digital's Caviar Green HDDs also have a horrendous failure rate. Stay away from both brands.
