It says 304mm or 10.9", 304mm is actually 11.9 inches, but to me it looks like the case has a 10.9" clearance for graphics cards, like many mid-tower cases.
Edit: I took another look and decided it manages space better than most mid-towers, so I Googled around and it looks like it's 11.9" or 304mm, so you should be good.
ok had me worried for a bit
. also can't I remove some of the hardrive cages fore more space / airflow?
