Can I remove my Macbook Pro's optical drive and leave the space empty?

Hey guys!

Anyone know if I can remove my Macbook Pro's optical drive and leave it empty? I just replaced my hardrive with an SSD and it is sufficient enough for space. I also never, ever use my optical drive and would prefer to remove it completely and leave it empty. I hate the sound it makes when my Pro boots up and now it boots up in seconds :)

Basically I'm asking,

-Is it safe i.e. dust collecting?

-Will the wiring be fine, or will it move around a lot?

Thanks for your help guys!
