The *good* think about that card is that even though it's an EK block, and their QC is suspect at *best*, chances are PowerColor would do their own QC, so hopefully you'd end up with a decent product.
But I kind of agree with the hampering though, purely because of rad space. A 240 rad is plenty for a stock 6900XT, but for those of us who've unlocked the power limit, a 240 won't cut it I bet. I'll know for sure once I block my 6900XT, but I can tell you than at 385W (stock is 272W), that thing throws off SERIOUS heat.
