*edit* There's not much of a price break on the 1kw ultra unit. it's only gong to cost me another 50-75 bucks to get the 1600w variety.
Also stargate - how much quieter is it than the PCP&C 1kw?
If the risks are alright with you, then go for it. Just make sure you register your PSU to get the lifetime warranty!
In terms of noise, the Ultra is down to the level of noise my case fans produce on low. (I am using the XtremeTurbine fans listed in my signature.) When using the 90+cfm-rated Silenx fans, the Ultra PSU was a tad bit louder than those fans on low. I only ever used the Turbo-cool with the default Thermaltake iCage fans, and the Thermaltake 120mm and 92mm SmartFans (which are loudest of all the fans I've mentioned so far). I would have to turn up the SmartFans to drown out the noise of the Turbo-cool.
As another comparison, I seem to recall that you used the Silverstone FM121 fans a lot. With that fan set on low in my Tuniq Tower 120, I can't hear it over any of the fans I am currently using, or the PSU. However, it doesn't take much increase in speed for the FM121 to out-scream the rest of my fans when on low, including the PSU. I also have a feeling that the FM121 would give the X3 a run for its money on low if I were using it as a case fan and not in my CPU cooler.
In other words, if you have your case fans on low (assuming they are any of the ones I've mentioned), you well definitely be able to tell the difference between the Turbo-cool and the Ultra X3, and it won't take much to drown out the X3's noise production in my experience, either.
Another thing I forgot to mention is that the X3 has the fan on the bottom side as opposed to the end, so make sure the PSU has good airflow from your case to keep the PSU cool.
