P Smith - The mechanical parts you photographed look identical to what's in my "E" version. Those three "bumps" are to strengthen that section, not for appearance or cooling. Strength is probably needed only for handling during assembly. I imagine that whole unit is pre-fabbed (bracket, HDD, fan) and it would tend to bend while handling without the reinforcement.
I agree with your comment re: the soft-mount bushings - needed for shock isolation and to reduce the noise from the HDD being coupled into the case to make the system a bit quieter.
Where did you find your HDD model number? I'll look closer at mine for comparison. I am not willing to remove that tape that covers one screw on the right side bracket mounting that says "Removal voids warranty" so I won't be removing the bracket/HDD/fan assembly, but I might be able to see a model number if I use a mirror.
I am looking into a heat sink/cooling fan for the BroadCom BCM7038 chip...
