Thanks guys, the questions mainly about whether they'll be compatibility problems (with value for money as a side note!).

Check your hardware against this list:

Personally my preference would be an Nvidia chipset graphics card, just make sure you dont buy any components that no one else has, otherwise youre on your own to get it working.
HTH

Cheers for that, never thought you might have a list!
