You should really be reading better to know what your doing rather than just jumping into it. If you want a parts list to have a look at with what you should use here's one:
Cpu block - D-Tek Fuzion
Thermochill or XSPC double rad (120.2)
A Laing DDC Pro with a custom top of your choice ( If you think you might want to add more later to the loop such as graphics block, chipset blocks or even mosfets might want to look at the ultra version of the pump)
Thats your core components just need to add T Line or a res for filling the loop and thats all.
