yeah... looks are fine, but unsound...
the drives are not grounded to the case... the case is definitely not grounded.
appears to have no EMI shielding, so it is not FCC compliant.
all, in all, no one ever listens to me when the clear craze broke out many moons ago.
to ground drives: use screws. use a single wire to connect the screws which are screwed into drives.
easier method for drive mounting, rails.
EMI shielding, metal mesh, one layer which is still see through is better than nothing.
