is being pumped up will be helped by the fluid inside the other line pushing down.
It's a bit like an elevator with a counterweight: The elevator's motors don't actually need to be able to lift the elevator,
they primarily need to overcome the friction in the mechanism (although in that case you'll obviously have differences
in mass between the counterweight and the elevator unless you adjust the weight each time when the cargo
changes, which is not likely).
Obviously this simplifies thing s a bit, and my fluid dynamics and mechanics are a bit rusty, but I hope it makes sense.
Thanks for the explanation and using the elevator imagery and yes it made total sense.

Actually I did kind of specify: The Res will be on the Mid-plate by the motherboard towards the top of the case and the pump would be in either the bottom of the original case or in the pedestal. Thanks for looking out for me though, but I know the only portion of the loop that the order counts on is from the Res to the pump.

It would be very Gravity Fed
Since posting the question earlier I was able to figure out where to mount my hard drive cage so that I don't need to get a Flex Bay Cage to put in the pedestal which frees up where I really wanted to put the pump. This problem came about because I'm going to use the stock hard drive location for other stuff.
Thank you everyone for the advice and the fluid dynamics lessons
