Vertaxis,
Thank you for the reply.
I am going to cut and paste the rather lengthy comment on the Kickstarter site to help explain. Please let me know if you have further questions, ideas or comments.

Jonathan,
Thank you for the comment.
Below is an except of an email response from me to a researcher in the Netherlands who is working on a similar project. I hope this answers some of your questions.
===========================================
Thank you for your kind words of advice and for sharing your experiences in such a similar project to our Kickstarter project. The guidance you have provided will advance our project significantly; we are truly thankful.
The below is intended to further describe the intent of our project. We do not go into this level of detail in the Kickstarter description because we believe that it will simply be too technical for most potential donors.
The schedule of "typical" components we have provided in the Newegg wish list is intended only to be an example of one possible solution to be used in determining the optimal configuration of hardware, OS, BIOS and BOINC client software. It is fully our intent to build five very different platforms in order to help determine the optimal configuration. Actually, we will likely "swap" components between systems in our attempt to determine the "optimal" configuration in terms of cost/performance. The optimized configuration will eventually be "blue printed" and provided as an "open source" document.
One specific example is that we intend to build comparable platforms based on X79 and Z77 motherboards to help determine if available PCI-E bandwidth creates a material bottleneck in this particular application -- and how such a choice may limit processor selection (e.g currently there is only a very limited selection of LGA 2011 processors) and the corollary effect of this limited processor selection on cost/performance.
We will also calculate the cost/performance benefit of running fewer GPUs across a larger number of PCs (as you suggest) and are considering testing a dual processor motherboard. Both Intel and AMD processors will be evaluated.
Further, it is our intent to test Windows vs. Unix operating systems. Oddly, most current "top producing PCs" for the BOINC client run either the Win7 or WinXP OS. We are unsure why this should be so and hope to determine the reason through this "head to head" testing.
Similarly, we intend to test 8GB, 16GB, 32GB RAM configurations (with various "speeds" and latencies); SSD vs. various hard drive configurations; and different GPUs. For example we may run two GTX 690s against four GTX680s against four GTX580s and will certainly compare nVidia vs.AMD/ATI performance.
We are indeed concerned about power requirements and heat dissipation. Our intent is attempt this project from our home so that we may have more time and freedom to modify the systems on a constant basis -- while keeping our day jobs

.
....
I certainly agree that the liquid cooling option is not required under normal operating conditions, however we intend to determine if overclocking the CPUs has a material advantage and our experience leads us to believe that enhanced CPU cooling can lead to greater stability / lower temps at high processor speeds/voltages. Also, LGA 2011 processors do not come with a "stock" cooling fan.
With regard to the other components (monitor, mice, optical drive, etc), we do understand that these are not absolutely necessary for the builds, but they do provide convenience (and maybe efficiency) as we run and rebuild these systems many times over the course of the year.
One thing that we have tried to make clear is that the $25,000 for hardware is a budget; our actual cost may be more or less. If it is less, the "extra" funds will be used to operate the project for a longer period of time; if the cost is more, we will meet our one year operating commitment, at our expense.
I would very much like to hear your thoughts on this more detailed description of the intent of the project and our overall plan. I welcome any further advice you are willing to offer.
Best Regards,
The Sheaffer Family
====================================================
To answer some of your additional questions:
The PCs will run nothing other than the BOINC client. with the possible exception of running benchmarking programs from time to time to assist in the optimization.
After the project is complete, we determine the disposition of the hardware. If funds allow, we may continue to run them indefinitely. Alternatively we may sell the components to build new platforms based on newer technology. Or we may donate them to other scientific pursuits. In any case the hardware (or value thereof) will be used exclusively for the advancement of science...we are simply unsure of what the best use may be a year and a half from now.
Our intent is to run the platforms from our home; however we do have real concerns about power consumption and heat dissipation. The advantage to running from our home is easy access and additional time for optimization. The downside is total power draw and power fluctuations inherent in our residential grid. - hence the UPS in the sample schedule of hardware.
However, I have access to a regional computing center that hosts mainframes and server farms and am certain that I can install the platforms in this facility for little or no cost beyond power consumption fees. So we do have a "Plan B". The downside is that that we will have to go to this facility to make any mods to the hardware, so optimization will clearly take longer.
I think the rest of your questions were answered in the cut and paste above, but if not, please just ask. We are happy to respond.
Thank you again for your interest in the project, for being a BOINC participant, and for your pledge.
