Dell Inspiron 17 (Model: 3737) How to remove DVD drive

On most laptops it's easy to remove a DVD drive, mostly you have to remove the bottom plate and remove 1 screw and that's it.

On this Dell Inspiron 17 (3737) however, I can only remove the bottom plate which contains the HDD and RAM.
I need to remvoe the DVD drive so I can replace it with a HDD caddy.

From what I've seen, the whole bottom has to be removed.
Is there anywhere a tech guide or something like that?

Since the most parts of made of plastic, 1 wrong move and it's broken :(

I can find a lot from Inspiron 17R's, but they look different...

Anyone?
