Honestly, if you think spending 100 dollars at a ups store to have it packed and sent to a competent builder, when you are spending 5k on a build.... is to much... then man .. there may be no point in advising you. But if you want to do it yourself, we learn best by doing.
The thing is, when you do a but load of research, you get obsessed with an idea, and with that obsession you ignore sensible advice.
I noticed that now you want to mount yet another rad in the case, where is the air flow going to come from?
BTW you will gain NOTHING ZIP ZILCH from three PUMPS, except heat dump, power consumption, noise, and a bunch of other undesirable things.
Take a look at vapors test, and temp vs flow rate on any block you may be looking at.. .above a certain point, there is nothing worthwhile gained, or what is gained, is within measurement errors, in other words statistically insignificant. Let say the gain is 1c, you gain as much from having one pump, and using indigo extreme instead of shin-etzu !
It happens that the best block, right now, is also one of the least restrictive.
My advice, dual loop, 3 radiators.
One top mounted quad rad ala koolance, (it works and it looks alot nicer with mesh instead of wire grills) for the cpu/chipset.
Two rads on the bottom, maybe quad rads, exhausting air, drawing air from the bottom of the case, a but load of gt-14 fans, and some aquacomputer gear to manage the mess.
Even a dual 140 mounted on top with just a standard rad grill will do the trick for the cpu.
At 4ghz you are probably looking at 200-250watts worse case scenario heatdump.
Blocks, basically EK.
Do tri-sli + phsx (gts 250, or 240)
I would put the phsyx card at the begining of the gpu loop for the lowest heat dump.
Two quad rads will more than take care of the heat.
Distilled water, biocide, silver kill coils, bp true silver components.
Pick which ever Res suit your fancy, but pick two. The bling is nice, but you may run into reliability issues.
Also... try.. KISS!! Keep it Simple ...
Hell you might even just send your case to origin. Let them do it, warranty it, etc!
But if you must spend 2 grand on w/c, you have to realize that you are going far beyond the point of diminishing returns.
How are you going to manage, and control your system? Are you planing to buy an aquaero, mcubed, or koolance monitoring system?
It's more important to make sure the rads that you do use are getting the right amount of airflow, not so much shoving as many rads as possible.
good luck with your build, i'm sure you will learn from it, and benifit from the experience. However don't be surprised if you end up having buyers remorse.
Truthfully, I'm sure that you could get by with 1 quad for the gpus, and a dual/triple for the cpu/mosfets. You're going to have a hell of time building everything, reserve a weekend and a case of 5 hour energy.
