I’ve seen computers modded into all kinds of crazy shit. (had a few friends a few years ago that were big into computer case modding.)
I’m sure you could do it.
However, i would suggest making some sort of frame on the inside and just screwing the binder into the fame. It will be far too weak if you just try to use the binder.
So what i would do is, pull the rings off the binder, and stick a strong wooden back where they were before. Then put another wooden block into where the opening would be, if you want a slight incline you will want to make it shorter than the back and cut a slant on the top. Of course after that you would add sides to it and make it sturdy. I would even suggest buying some plastic to screw on top of the wood and under the binder so that the stick can be firmly in place. The binder would be really weak and probably couldn’t hold up to the stress of use without making an inner shell first.
I do think its possible, but it would be extremely difficult. Its gonna take a lot of planning and modding experience to get it to work.
