This might sound like a dumb question but I am replacing the bottom plate on my 2015 retina with a GPU and when I got my replacement backplate I noticed that it didn’t have the cutouts on the bottom for the GPU. Will this be a problem or does it not matter?

Let me put it to you this way… Your car tires are quite worn almost with no tread, would you go on a long trip on them, how about a very short trip? Sadly this is a similar issue, if you are a heavy graphics I would get the correct bottom cover.
