ok, to clarify, I wasn't suggesting connecting the res directly to the pump's inlet, although that is a good way of lowering the restrictiveness of the loop. the top of case location is good. if you haven't already, check out pH's article on making a more effective cooling loop in the procooling articles section. that expains the science behind some of the stuff.

@ jabo - pressure drop doesn't matter like you're thinking it does. it will be important to figure the overall pressure drop since that will determine the overall flow rate through the loop, but its not important to determining where to place say the block vs. the rad, since the flow rate is the same through the entire loop regardless of the restrictiveness of the individual parts. does that make sense? hmmm, guess i kinda contradicted my earlier post, ah screw it, do whatever gets you the best temps.
