1) that sounds good but the hr-09 wont fit the board, and the stock sink works great with mx2

2) on liquid the q6700 is better

3) ocz flex is bad its aluminum, and restricts flow and since power chips dont get hot its not worth it, and u cant go 4x1GB unless u want to spend alot of money on ghm and with liquid on teh cpu the fsb will be high enough that the powerchips that only do cas 5 will be good. i like the gskill non pi
