There is a minor issue however; the cover starts to rattle occasionally from vibrations caused by fans with higher rotational speeds. It is unlikely you can still hear it over the combined choir coming from within your case; but if the rattling somehow still manages to bother you, tapping on the cover would silence it.

 

It seems to us that the design team from Prolimatech are avid fans of the Transformer franchise.
