I read up a little bit but there's way too much information and I just get bored reading,
the CLC's are also covered in that sticky. Its your call, you want to be spoonfed by total strangers. How do you plan to tackle a problem should it arise? via a skype conference call?

I don't think the 240mm radiator will fit because of a heatsink near the CPU that's already blocking the 120mm fans I have on top.
if you think it won't fit, try thinking outside the box.
Can I go for a 120mm radiator or should I just go for a closed loop water cooling like the Antec 920 or the H80?
don't want to go there
