yeah they do tend to have some issues with internal space in certain models of Antec cases but this one was given the update with the 900-2. Its just a shame its aesthetically a lot less appealing than the original. Which is why i chose to still go for it. As far as fan cooled cases go, its still right at the top. With its 5 90mm fans and the huge vacuum fan on the roof. I'm still not trusting enough to go watercooled. So this will do just fine..
