Want cheap and low cost htpc and spec check

[medicalgiant]

I am looking at a htpc upgrade, but I want it to use less power and make less noise. Have I chosen the correct parts? Are there any ammendments I can make?

I want to use it for recording freeview tv, using MCE2005 watching downloaded material and surfing the internet when required.
