I like the setup alot, but then again, I may be biased.
In my case I used the V1200B because I knew I'd be installing two loops and as it was my first WC rig, I figure a little too much space is better than not enough space.
I didn't worry too much about the restrictive nature of the NV68 blocks as I used two modified Laing DDC pumps in two separate loops.
And after doing a lot of reading, I'll agree it seems like overkill.
But anyone who is willing to purchase a pair of $725.00 video cards is probably not going to mind spending another $250 for a pair of NV-68s

One thing possibly "wrong" with the setup as you see it depicted above - which I may or may not correct - is that I have the flow to the TDX such that the inlet is above the outlet. I realized that such could be a potential problem after I put everything together.
So far, even if I introduce air into the system on purpose, any entrapment that momentarily appears at the TDX seems to disappear almost immediately.
With the two mod'ded pumps, even though I can't measure anything related to flow and pressure, it seems like I have enough of both.
I used both a Danger Den fill tube and a reservoir.
The fill tube is located directly above the fill port of the reservoir and connected with a very short length of tubing.

A couple of additional gratuitous shots . . .

Last challenge will be to install a Plexi window on the side. The 1200 is not yet available with a "factory" window treatment.
I am going to swap-out the fan on the CPU outboard loop for a Stealth fan which will provide over 50 CFM @ 1500 RPM.
One thing I learned along the way is that the system above works well with all three fans running at 50% RPM and overall, the system is very quiet.
Someone around here commented recently that we need not worry about fan speed controllers if we pick the correct fans in the first place . . .
. . . but how are some of us n00bs to know?
Those two ground straps you see on the Evercool fans are there for good reason, ah but that's another story.
