I'm pretty happy with mine still, I've just had it in bits upgrading the hot swap drives bays and sorting out LEDs behind the reservoir but it's pretty much got everything in I could possibly do now.
Roy, I understand, when I started out I was looking at the H70 as it looks like a good option, the cost of going for a full WC solution can easily mount up (i think I must of spent £200 in fittings alone) but the end result is worth it.
SR-2 is a beast, but I'd rather spend the money on a more complete overall system inc WC.
Out of interest what's wrong with Dual GPU over Single?
