Not entirely sure what you are looking to do with it, but a ceton DCT would also be an awesome addition to it. I own its predicessor and it basically turns my media PC into a HD-DVR for my cable as well. You rent a cable card from your cable company (stupid DRM) and then you have a fully functioning and expandable Tivo in addition to an internet capable PC. Plus you can watch the content you record on other computers in the same network

.
SSD is also an awesome Idea. Especially with the setup above because who wants to wait two whole minutes to watch TV, sit down, hit the power button on the remote, and blam, watching that episode of archer you told it to record yesterday
P.S. IR Blaster is key, no getting off the couch required.
