Welcome to the club!
Some of us ran the onboard graphics while we worked through decision making as to which graphics card to buy. LA_KINGS_Fan can help to get you added to the front page.
He will likely pitch the Saffire Toxic HD6950 as a good choice, too! His unlocked - I am still working to get mine installed...
Lots of Corsair Hydro Series coolers, H60, H80 and a few H100 systems. For the H60s, I suggest push/pull fan set-ups. I think there are some Hyper 212+ set-ups represented, too. If you post your system specifics (try the Quick Links" button at the top left of the page) it you will get more informed responses concerning air coolers, too.
Good luck with the build and welcome!
Just a little more info. I was looking at the Antec Kuhler h2o 620 CPU cooler, but firstly I'm sure it uses a 120mm fan and the case I'm looking at getting only has 60mm exhausts:
Am I right in thinking that the 120mm fan from the Kuhler will be too big for this case?
