Can I take the optical drive out of my MacBook Pro?
Yes, it is possible to remove the optical drive. However, it isn't that easy. You will need several specialized screwdrivers, a tool to remove the cables, and some manual dexterity. If you have experience disassembling laptops it will not be a problem.

Go to ifixit.com and find the instructions for your model. 

Side note #1: this would be a good time to change the spinning drive for an SSD. 

Side note #2: I don't find the price of MacBooks these days to be excessive. Have you seen the junk you get for $500?
