That was one of the things that I wasn't so clear on.. I must have looked over that artical 20 times.. And that's where I wasn't sure if the gts would be fine in push or better in p/p. There is a review on Amazon a guy used the mcp50x pump only for the r220 and he had some caveats about it.. Which is what I was gonna do...i want it to be simple and elegant.. Lol.. So using the gts in push only with the 140mps and the halos will be just what Im looking for.. That aquacomputer vision is sooooo nice.. But I'm also considering doing the Aida 64 cell phone mod.. So I could technically keep it all phanteks.. But the aquacomputer cpu blocks seem to be higher quality.
