As a former enthusiast in the liquid and vapor phase-change cooling market, I can point out a multitude of things gone wrong here.

1) Single Cooling Loop - with 4 quad-core processors, this machine could net much better bang-for-the-decibel out of a dual loop system - one loop handling one pair of processors, second loop handling the other pair. Optimally speaking, a quad-loop system (individual loops per processor) would net even better results.
2) Video cards have fans, too! - Find yourself a video card that uses cooling pipes or similar technology, rather than fans. Those little fans spinning really fast make _LOTS_ of noise.
3) Speaking of noise - WD300 Raptors? Congrats, you just put the noisiest modern hard drives in a machine "built to be quiet" - if no expense was to be spared, why is this thing not outfitted with Solid State Disks???
4) Problems with the liquid - in addition to number one above, the reservoir is mounted at the bottom of the case? That's an amateur mistake right there. Reservoir at top of case = any air infiltration gets trapped at the reservoir. Additionally, the "angled barbs" are 90-degree bends - not exactly what you want in a low-flow system, backpressure is going to kill that pump, or at least cause it to whine incessantly, even at lower flow settings.
5) PSU - Corsair HX 1000W PSU - why not a PC Power and Cooling ultra-quiet unit, or a SilenX-modded solid cap PSU? Instead, they opt for a PSU rated at 57dBm?

Amateur job, Puget, very amateur. If anyone feels the need to build a super-quiet box, they really should shop around and look into these type of issue, or suffer sever disappointment.

Sun's hardware is already prohibitively expensive, how much will options like this add to the price of hardware? When I can order up a pair 4U boxen from any competitor that each have the same hardware specifications as a single box from Sun, what does this buy me besides simplified wiring/management, and the ability to run Solaris?

I guess I'm one in 600+Million then... When you've got a big fat pipe and a couple thousand CDs in your collection, you quickly find that .torrent is a LOT faster than swapping discs through the ripping machine. If it matters at all, this is a consequence of my earlier work as a DJ - over 3500 CDs spread through almost a dozen CD books that each have slots for 512 discs.

Maybe they're hosting the article with pictures on one of these $10 laptops? ;)

Could be worse, at least they're not watching soaps from the Philippines. Do yourself a favor and subscribe to any Pinoy channel on cable/dish networks, it's nothing but 24/7 soap operas (and as a bonus, usually in English instead of Tagalog!)

So this is a miniaturization of the peltier effect, with the upside of supercooling one side of the film, but how do you extract the heat from the opposite side of the film? Without a large surface area and volume, liquid-cooling the opposite side may not suffice for thermal transfer...
