After testing the Orchestra, I can quite confidently say that this new product brings healthy competition to the passive watercooling market, and beats many of today's offerings. With the new CPUs hitting the market, chip manufacturers are constantly working on making more effective architectures that produce less and less heat. The Orchestra takes care of the heat without any problems.
Thermaltake's Orchestra is very newbie-friendly, even if you have zero experience with watercooling, you will find setting up the kit as easy as pie. Due to the fact that I run watercooling already, and my block mounting is compatible with Thermaltake's, installation was lightning fast - about 15 minutes.
Even though Thermaltake uses very small ID tubing throughout the kit, the radiator design is very well thought out, and overall performance is good. The only thing that I have to complain about is using aluminum and copper in a water loop. Even though the coolant contains anti-corrosive additives, this is still not the best option, and galvanic corrosion develops. Manufacturing the radiator out of copper would have been insanely expensive, so that wouldn't be any good either. I am glad that Thermaltake is taking the comments of reviewers seriously, and is upgrading their product to meet highest standards.
I was satisfied with the performance of the unit, as well as it being completely silent. It is definitely a change from what I am used to normally (7W fans at full blast aren't the most silent thing you come across, as most will confirm). At first, I was worried that the unit would have problems dissipating heat that built up over time, but our two hour tests proved this assumption to be false.

On a final note, I would not hesitate to recommend this unit to anybody. It does what it is supposed to, at $200 it isn't exactly cheap, but the price is well justified for what it does.
