I was eyeing the case until I read about the shipping weight in the specs list on Newegg. I'd have to pay about 10 USD per pound for anything I'd like to ship from the States.
That is a spanking new build G-unit!

Kudos...
If you're not going on an SLI setup better look towards the NEX650G/750G units, they are fully modular or better yet look into the Platinum rated PSU's from Seasonic or Rosewill.
Since your case allows it, I'd opt out of a AIO cooling unit and dip into custom cooling
But that system is fine as is
