I got a XFX RX RS 480 that was 9.5 inches, so within the size limit (without removing the cage) but this model is objectively inferior to the XFX GTR (which is around 11 inches long) due to the latter's much better cooling. I'm thinking of refunding the RS and getting the GTR, but my case's length limit is only up to 10.6 inches, unless I remove the cage and that gives me 15 inches to work with. Any guide on how to do this?
