looks interesting...
I've currently got the plus 1 running in my setup (P4 2.8 @ 3Ghz, 6800ultra) quite nicely (~ 5 C lower than air), although I'm looking to build a complete new system come nov/dec time based off conroe and whatever graphics card suits my needs at the time.
I was planning to use the plus 1 I have already on the new system as in theory the new system shouldn't give out any more heat that what I'm currently running.
However I may well consider the reserator 2 depending on the improvement in performance, only downside is that it doesn't look anywhere near as funky as the original.
