Cheers Jaydee, I guess I did too much reading and not enough understanding. The T pipe with the filler pot on the top of the case will negate opening the case to fill system; useful, especially on the dual Xeon system as the resevoir will be under the radiator on top of the case. I didn't know about manifolds until recently, they seem like a good idea at the time
I have since added a shurflo filter.
Another quick query, how many things can I add to either system ? Will my pumps handle a graphics card cooler on the duallie or two on the the Storm system? Thanks again for sharing your knowledge
