I have an Antec 900 with a HIS X1959 Pro in it. I've just measured the gap between the tail end of the graphics card and the first obstruction at the rear of the HDD cages. There's about 45mm to play with (and that's to the back of my deepest-reaching optical drive).
As for cooling in the Antec 900 - I can't fault it. There's lots of possible configurations and, with a fan controller, you can go from quiet idle (for web-surfing) to an impersonation of the Red Arrows in a tunnel (for those much more demanding applications).
