^It's true, I jumped on the same deal, and bought a mcw80 like 2 days later, I also got a replacement heatsink w/ it because it was $8 more than just the mcw82.
I got the wrong bracket w/ mine, so i emailed Gabe over at swiftech, and they are sending me the updated rev2 bracket. After talking to him I decided to send in my mcw80 to get it machined for mcw82 design spec. Allows better waterflow similar to the mcw60. All i have to do is pay to ship it back and forth to swiftech, USPS so it's not too bad, but I will have to wait.
type mcw80 followed by gtx 470 into google and go to the first link, I'd just link to it for you, but I"m not sure if I'm suppposed to link to other forums..I haven't read the TOS. there is a guy that did exactly what you are trying to do w/ a mcw80. I'm sure you could manage to do the same w/ the xspc block if you get that one too.
