I just built a PC in the Elite 130. When I went to install my MSI GTX 1060 6GB card, it was too tall to fit under the 5.25" drive bay. I had to remove the drive bay by drilling out the rivets.
Use screws to attach the 5.25" drive bay so that it's easily removable.
Include one or more optional horizontal mounting racks across the top of the case (like the vertical cage, but across the top), to provide mounting points for more drives if the drive bay is removed.
Other than that, it's a great case.
