Spec check please before ordering!

Already bought a Silverstone Fortress FT01 case and don't need monitor, keyboard, mouse or OS. How does the below spec look and is there anyway I can improve it?

Thanks for the advice chaps. I would get the BeQuiet 650W but no stock at the moment so decided to get the 750W. Always better to have a bit extra than not enough (or so the missus says). Also changed the Ram to this so I know they can go next to each other.

Any other problems you can see before I order?

Cheers
