Laptop dangerous with missing CD reader?

My laptop does not have a cd reader because I've upgraded it because it is too loud now I wanted to know if this is harmful if I accidentally touch it on the silver could I get an electric shock? (Fatal)

Wait, he's too loud for you even though he was off in the laptop?

Um no but what silver ones?

Probably not, the real problem is the dust that lands inside your laptop. I can advise you rather to leave the drive installed, and simply not to connect the plug.
