Anyone have any experience with newer universal gpu blocks?

[HiTi]

I want to try some universal gpu blocks on my 6870's in xfire...as I can see me proby getting another video card in the near future, otherwise I would go full coverage.
I was looking at the rasa, ek supreme vga, and the mcw-82.
So basically, looking for maybe a nudge in the right direction.I just figure if I get the universal I can carry it over to the next gpu...rather then try to sell a 6870 only block.

I'd probably go for the MCW-82's. I was thinking about buying a bunch for some HD5830s in a mining machine. Supposedly the flow is much more like the MCW60, which was a fantastic block.

I'm using EK univeral vga blocks on each of my 3 gtx 470's. At stock speeds the cards never go above 44 degrees. Plumbing them in was awkward though. Worked out in the end, but I personally wouldn't use the universal blocks for multiple card setups in the future; just too hard to plumb them in IMO.
