FWIW, I'm looking into getting this same case for a build. The CLC is the cooling method I'm thinking of using, too. I thought these three would be decent contenders.
Antec Kuhler 620
Corsair Seidon 120V
Except, I really don't like using typical power supplies so I'm looking at modular and there's not much choice. So, looking at the Silverstone ST45SF-G and adding the flat modular cable kit, PP05-E, to enhance cooling (hopefully) - even though Silverstone should include these cables!
The H60 is pretty popular around here for a basic CLC for these SFF cases. You can also replace the included fan with something else, too.
