I really want the Inwin 805, like really badly, but I have a gtx980ti Lightning from MSI, and its total length is 12.99 inches, or 329mm. Is there an extra 9mm of space anywhere, or when they say 320mm of clearance do they mean there is EXACTLY 320mm? I'd assume they'd undercut themselves to avoid any issues but I'm not certain. I definitely do NOT want to mutilate either my beautiful gfx card or this beautiful case.
