Best place to look is the general gallery on this site, and read through the comments in the threads. There will be a few particularly good ones out there, but I don't have the chance to sort through them and highlight examples.

But it did fail in disipating the heat that all the componets that I was trying to cool generated. So I dismantled the unit, sold the vapochill and the chassis and the blocks and kept the pump and res and manifold and the documentation that I had generated.
That's good. Maybe I overreacted to your early posts (if so, sorry for that) - I've been having a fairly dire week and that may have coloured how I read your posts.

Partly, many things have already been tried and people know the results - you may or may not actually be innovating and not know it. Partly, with complex systems unless you have the sort of test equipment BillA has lying around you won't be able to work out where the problem is in a system.

Actual helpfull material.
Fair enough - that's a good way of going about it. You might get more help/a friendlier reception in future if you're a little more careful in how you phrase it however - just about everyone thought you were saying something you didn't intend to say.

First off: My pump is a Pondmaster 5 now as for GPM and Ft/Head? From what I have read about pumps, The pumps that are used for different applications have different ratings per application. So I'm going to assume that the Ft/Head is the term used to relate to how much flow the pump can push for a certain lenth or run of tube.
OK, by "Pondmaster 5" do you mean Model 5 Magnetic drive, code number 02515? If so, it seems to have pretty similar specifications in the flow regime you're likely to be running in to the Danner Mag 3, one of the more popular watercooling pumps. This is going by Phaestus' pump comparison article and the spec sheet you linked to, but should be reasonably accurate. (Pondmaster seem to be a trade name for Danner anyway).
All the water blocks, tubing, radiator and the like in your system will have some resistance to flow. This will take the form of a pressure drop between entry and exit, and is measured in terms of what vertical height of water will give the same pressure difference between the top and bottom of the column. In the case of what I think is your pump, the pressure difference it can sustain seems to be 10'6", or a bit over 3m.
What you usually have is a line on the pressure/flow rate graph showing the pressure/head characteristics for various pumps, and another line showing the same characteristics for your loop (i.e. due to tubing, blocks and the like). The point they meet at will be the operating characteristic for the pump, and using this you will be able to predict the most suitable pump for your system in terms of water pushed versus heat dumped into the system by the pump. Cathar has done a very good thread on that around here, with some very useful graphs.

Not sure about the radiator (distinct lack of radiator testing about), but the waterblock doesn't look promising. Internally it is basically a "maze" style waterblock (i.e. water flows in, around the block through a channel and out again). What ProCooling test data there is (for the DD Maze 4) shows it to be beaten by several degrees by many more modern blocks, and my gut feeling (not backed up by any test data) is that the Maze 4 will have a higher performance than this ThermalTake block.
Link to the comparative block testing here: http://www.procooling.com/html/pro_testing.php
If you want the rationale behind my thinking the maze blocks all behave similarly, go to Overclockers Australia and read Cathar's WhiteWater development thread (there's a link in one of the stickies). It's something like 45 pages long but quite entertaining and explains why the newer "impingement" blocks perform so much better very well indeed

I would think not but rather someone might come along that can disipate the same heat but with less hardware. ahh, isn't that what this whole thing is about simplicity and acheiving the same goal, Heat disipation in the most simplistic but yeat efficient way?
Series isn't the key - for instance if you had three replica loops, each dedicated to cooling either the CPU, GPU or Northbridge that would perform better than a single one of those loops cooling all three. The thing is that the difference isn't all that great and to do this you've trebled your cost and space requirements. If you start compromising, in most cases the series loop will win, as the performance differences are minor and the cost differences quite major in comparison.
