I would look into an Antec 900 or Antec P180-182 series. All those are full cable of what you are gonna be using. They also have great airflow. The P Series is quieter. Good luck.
I don't believe in wasting money on a case as it's just a box that stops the bit's from flapping in the breeze, much better to concentrate the cash on the bits inside the case.
The better the cases the cooler your parts. Its a fact that the higher temp your parts get the lower performance you will get.
paying 2000 dollars for a pc and cheaping out on the case only to have your computer overheat/ Parts not fit is wasting your money
I don't subscribe to your theory as I've always used the cheapest case I could lay my paws on and compared to users on this forum who have posted their temps mine are amongst the lowest and I don't do W/C.
Antecs are good to fit an 8800 gtx as i am also in the process of building a new unit. Personnally i like the zalman faitality. 2x92mm fans going in 120mm fan going out. A bit pricey here though.
