Would 2 240mm rads be anough for a CPU and GPU? By the way, price isn't a problem.
Yes. You could get by on a single 3x120 if you really wanted, but I think I remember that size not fitting your case.
Edit: for clarification...
240 = 2x140 or 2x120? In the case of the XSPC rads, they are 240, 260 but all for 120mm fans, I believe. Typically, a basic rule for rad sizing in a forum is 220 = 2x120, 240=2x140. It doesn't help when manufacturers confuse things with different model numbers that don't necessarily correspond to the rad's actual size.
