Hmmm... dare I comment..?
As you may have seen in other threads, it's very easy to get confused about such matters. There are many models/abstractions that can be made for a system, and the challenge is picking the one that illuminates the matter at hand.
With that in mind, I'll humbly suggest that "flow" is the correct concept to use in this case.
Caveat: The following opinion comes not from watercooling, but experience in analagous systems, like electronics. (flow = current, pressure = voltage, constriction = resistance) I'm not selling anything, just sharing my insights in hopes of friendly discussion. If you do not value them, your money cheerfully refunded. Feel free to disagree or challenge my ideas, but please don't attack me.
I have a cat to support.
That said, if one accepts that flow is constant at all points in the system, and temperature near-constant, it follows that component order in itself doesn't matter much. The exception being that the pump should be right after the reservoir, so it gets bubble-free water, and doesn't have suction at it's inlet. (I believe pumps are better at blowing than sucking. Am i wrong?
)
I know that some people will say that order matters a great deal, and I may be wrong, but I just can't see why it should, and I'm thinking that the variations folks have seen may be random, or due to something else. :***:
On the other hand, hose length, and sharp bends definitely will add resistance, slow flow, and reduce performance.
So, what's the use of all this rambling? I suggest you concentrate on placing your reservoir before your pump, and arranging components to minimize tube length and bending. It also might be handy for filling and bleeding and stuff, to have your reservoir at the high point in your loop.
But the prevailing wisdom is that reservoir-pump-rad-wb is the way to go. Many people believe that makes a difference.
