I was just at the store looking at some cases and for my future build(I was looking particularly at the 900). I was surprised the 900 looked a bit smaller and tigther in the inside then I thought it would be. I toke a rough estimation on the size of a 8800 gtx(one was on display nearby) and figured it would just barely fit. My fear is if future GPUs grow in size even half an inch, Im not sure the antec 900 would fit it in. Anyone with a 900 wanna comment on the fitting inside the case, maybe it was just my imagination.
