The exterior aesthetics of this case are a bit hit and miss/love it or hate it sort of thing, but the interior is very solid, well thought out, high quality etc:
Lancool PC-K63 $100 ($6 shipping) http://www.newegg.com/Product/Product.aspx?Item=N82E168...
So if you do like how it looks then it would also be a solid choice.
I would go for an Antec 900, in this scenario, just for the quality build, the material and the airflow management. But frankly I just go with Antec 300; it is more cramped though if your thinking of WC not the case for you, but if you stick with air cooled, even with the largest gpus, you'll be fine (may require some minor modding for a 6990 though).
