Lately I've bought a brand new antec one case. I had in mind a sapphire r9 270x because it what fits the case. Today my friend sent me a deal for a brand new sapphire r9 290 4gb oc. I figured it won't fit since it's 10.9 inch and my case supports 10.5, but after looking online I've seen a few people fitting a sapphire hd5870 1gb. After a bit of research I found out that card is 11.14 inch (correct me if I'm wrong please). So should I go for it? Worst case I can mod the case.
