Regarding the old water cooling unit just get rid of it, how ever check the pump! I've had a few come that were Liang DDC type pumps which you can sell for a nice bit of cash : ]
By the way the antec kuhler 920 performs slightly better than the H70 if you have room for it
They are the exact same product one just ships with a usb cord. Th h70's testing is a bit flawed if you look at the testing room he has a 10C temp difference between the 920 and h70.
