My only problem with the case is the fact that the side padding was a lot thinner than I expected. I think it must have something to do with the side window version.
Coming from a Haf X to this was night and day. That HAF X was like a leaf blower with all the fans and little noise dampening. Now I just need to think of what to do with that massive piece of metal. I've actually been thinking of scrapping the metal to make a custom vertical HDD mount for this R4.
