Why can't I use an internal hard drive for backups?

Internal hard drives are significantly cheaper than external hard drives, so this is my question: is there a reason that I would really need to use an external hard drive for backing up data instead of an internal one? Wouldn't it be acceptable for me to just use an internal HDD for this purpose?

I could keep the internal hard drive in its own place when I'm not using it. When I want to read or write to it I just turn off the computer, open the case, and put the drive in. Then when I'm done I can take it back out. The only thing I see about external drives is that they make it slightly easier to connect to the computer; also, laptop users usually can't have two drives inside. But opening the case really isn't that hard, and the other thing only applies to laptops.

You can do that. I bought a 2TB hard drive just for backups. Cost me a whole whopping $70. I figure I now have the ability to store over about 10 backups, which should be far more than I will ever really need.
Perfectly fine to use another hard drive internal to your system for Backups.

Or if you wish you could fit a hard drive caddy into one of your free 5 1/4 bays so you can access the hard drive and swap it out later for a larger sized drive ect without having to open your case to get to the hard drive if you wanted convenience to access the hard drive for quick drive swapping.
A caddy will fit a standard internal 3.5" hard drive no problem. And convenient like said.
