According to the specs, it's a mm too long. All of these will, within the same price range:

Having said that, there's at least one Amazon reviewer that fit it in, and there are at least a few posters on various forums who say they fit cards a couple mm longer than the Sapphire 290 into the same case. You can play it safe and go by spec, or you can take a chance.
Personally, having no experience with that case but looking at the pics, I think that if you do it slow and careful, you can make it work, but that's just my two cents. That and someone else's buck fifty will get you a cup of coffee
