I'm not sure where you could put it in your HAF.
2. EK's blocks are good, Heatkiller, Aquacomputer, or Koolance are all OK. They'll all do the same, it's really about how you want your block to look. I think that XSPC's new 7970 Razor might match your Rasa better than other blocks (but I don't know about how nice that block is), but it's up to you. Bitspower fittings are the best, Enzotech are also really good. Monsoons have been getting more and more popular, but I'm not a fan of how their collars get stuck to the barb's threads.
3. Nothing on that, but I'm sure if something goes wrong you could just slip the original air cooler back on, keep the original thermal pads, and hope they don't notice.
I switched over to the Haf 932 case, so a 240 and 360 shouldn't be a problem, i can go:
The only thing about the xspc is, it doesn't cover the vrm, I was looking at the Koolance VID-AR797, but hadn't read too many reviews either. I'm not really concerned about the looks of the block but rather the noise/cooling performance. I can't stand the noise level of the 7970 at 50-60%. Will the fitting size that came with the kit work with the added card? Also will i need a backplate?
