I love NaeKuh, but I have to say that I totally disagree with his argument that in terms of computers and water cooling, you have to "go big, or go home". And I totally agree with RoadconeTuning, Kadett, and Antioch that water cooling less than the most expensive components makes sense. A P55 board with an i5 Lynnfield with a single HD 5850, is an excellent choice, and it makes sense to water cool such a rig for all of the reasons stated above by RoadconeTuning, Kadett, and Antioch, so I won't repeat those arguments here.

IMHO, the purpose of water cooling is to push the the performance of the components we buy way beyond what their manufacturers intended. This is the same motivation behind overclocking in general, to get more than what you paid for, to get top shelf performance at a bottom shelf price. Overclocking however generates heat, and water cooling is the most efficient way to remove that extra heat. So why not water cool an i5? If you are one of the people who feel that the i5 + P55 platform is a better value than the i7 +X58 platform, why are you not allowed to water cool it? Assuming the water cooling costs are the same, are you not still saving money by water cooling the i5 + P55 platform? The argument that you must buy the i7 +X58 platform and air cool it, does not make sense to me.

Now NaeKuh is absolutely right that the water block makers should only make blocks with the highest profit potential, and he may even be right that the highest profit potential is to make blocks only for the i7 +X58 platform crowd, because they presumably have more disposable income to spend (because they are richer). However, I would not be so quick to eliminate the i5 + P55 platform people from my potential customer base as impoverished peasants either. There are always going to be more peasants than noblemen. So it might be true that you can sell a few expensive X58 blocks to some rich folks, but you might also be able to sell a lot more less expensive P55 blocks to the more middle class people. This however is really a business decision, with considerable business risk, and the seller would have to sell a lot of P55 blocks in order to lower the price through the lower marginal cost created by high volume sales.

So what am I saying? In a perfect world, I would like to see a P55 block. However, in reality it might not be feasible. X58 people will pay $100+ for a full coverage water block. But will P55 people pay that? Are there enough P55 customers to justify a $50 price for a full coverage block? I have no idea, and I am not in a position to make this kind of business decision, but maybe Eddy at EK, or the boys in Taiwan will try it.

Last thing: On a personal note, I am right now thinking about water cooling a $99 AMD Propus quad core. The main reason for doing it, is that NaeKuh is going to hate it! I think it will cost $500 for the computer parts, and $500 for the water cooling parts. Not to mention the case which could be another $500! iNsan3? Not to me, it makes perfect sense.
