Replacing my macbook pro's optical drive with a second harddrive, is it write for me?

Hey, I have a macbook pro, 13 inch, late 2011. Well, I ordered a harddrive caddy tray that is used to replace my computer's superdrive with a secondary harddrive. It shiped and should come around this next coming Tuesday. However, I'm having trouble deciding weather or not to replace the superdrive with another harddrive. The reasons are:. 1. I wouldn't be able to use bootcamp to install windows on my mac should the desire come. 2. The stepps that are required to do this involve temporarily disconnecting cables. Those being the wifi, web cam, Bluetooth, and the right speaker subwoofer cables. I will probably have a technician at the Mac Life store in Boise do it for me. However, that still leaves the first concerned, what about installing windows along side os ten? I've used macs for years and know that, because the older macbook pros come with a built in optical drive, the EFI firmware will not allow booting from a windows installation usb flash drive. Any answers? I'm having a little bit of trouble deciding weather or not to do this. Any help would be greatly appreciated. Thanks in advance. Oh, and their is 1 more reason I forgot to mention as far as why I'm having trouble weather or not to do this. 3. What if the harddrive in the optical Drive bay failes or the mac has a problem with it? In case you all don't know this, I'm blind, and I really don't want to have to open my mac and try to install a different harddrive in the optical drive bay and risk breaking things. Anyway, again, any help would be greatly appreciated. Again, thanks in advance.
