I know you're not using the PSU at the bottom of the case, but remember to remove the small [ bracket shape at the bottom and have it powder coated separate so that if you need to move it, you won't show bare aluminum where it once stood.

May I also suggest popping the top where your radiator is mounted in the 5.25" bays? It's only four rivets and it will give you the option of mounting a thermochill if you ever feel the need.

Would be easy to re-attach it with rivets.
