Lost at WaterWorld.

So is this all I need to do for my inline water-cooled system with no reservoir:
After lapping the Waterblock for my (P4 2.4+ Gig) CPU, for a smooth surface &
After using the Dow Corning kit on my (Asus P4S533), for condensation protection &
After using the Artic Silver Thermal Compound, for a seamless layer for the waterblock.
Then I put it in my (Chieftec DX-01BD Black Server) Case.
I use the Y splitter to bring fresh water to my CPU and to my Northbridge, at the same time, and from my Northbridge to my GPU and bring them back together with the second Y splitter to my pump and back to the Heater core?

I’d hate to be halfway through it and find that I forgot something that was terribly important.

that sounds right to me

you insulated? are you using some kind of below ambient setup?
one thing I suggest is go to the cpu with all the water, then split it in half, one to the gpu and 1 to the north bridge then bring them back, that way the cpu gets full flow
