well... not sure on the 1tb thing

but really if your going for just a media center i would look at some other options.
Like a Divx Xvid/Mkv player etc etc
or even get a Ps3 or 360 and just convert the video/movie files to support PS3 or 360 (with PS3 you can even setup a Stream from PC to PS3 and video files are Auto converted As they play)
