3.I am not sure what you are talking about but the dimension of each different waterblock is easily found on their prospectice websites
4.Default voltage in the bios is around 1.4v

Good luck on your build.

1. I guess I mean what is the material of the actual heat spreader on the CPU (whatever the exposed surface is that the heatsink/fan connects to)?
2. Good, 300 GPH was my baseline.
3. Just the heat transfer area on top of the CPU piece - the same piece that I'm asking about in #1. Where can I find the product spec sheets you speak of?
4. I know my voltage, but how do I back out a power consumption from that?

I'll draw up my design at some point, but I'm not sure when I'll get time. The next two weeks are extremely busy.

So I lied. I drew up a basic schematic of one possible CPU waterblock idea that I have. I didn't type up the entire procedure for figuring out what I show, but I can do so if people actually care. Sorry for the quality of the web page - I just auto-generated using Word because I'm too lazy to write it from scratch tonight.

I also neglected to define my terms in the write-up, so here they are:

rho (looks like a P) is water density (~1000 kg/m^3)
Cp is the water heat capacity (~4.18 J/g-°C)
Q is the volumetric flowrate (300 gph)
T0 is the input temperature (chosen as 25°C)
T1 is the output temperature (calculated as ~25.2°C)
Pcpu is the CPU's power consumption (and, therefore, heat generation) rate (chosen as 150 W, but I don't know how close to reasonable this is)

Anyway, let me know if you guys are interested in this type of writeup and I can either not waste my time doing it anymore or I can waste more time and go into greater detail. I have another design idea for the waterblock that I actually came up with first, but I thought I'd write this one up first as it's much simpler and easier to understand.
