Thats a terrible idea you might need those for some reason in the future and the only way to assure you don't is by keeping them forever and making them your next of kins problem.
but yeah my current setup also happens to play games and adding storage is much easier cuz I can just throw whatever in there instead of making sure the drive conforms to some arbitrary crap.
I have an old dell power edge that I got from work that I used as a NAS for a while, it sucked down more juice than the old PC I was using and was stupidly loud all the time. I ended up transferring everything back to my old PC and now that turd just sits there waiting for someone else to be dumb enough to buy it from me. I wouldn't waste the money personally.
You are forced to agree if you want to play it, this is how shady companies operate. Now that you have agreed to it there is nothing stopping them from adding it in an"update".
If you think a shady ass company like epic wouldnt do that you are very naive.
If someone can kick you out of your house because you painted your fence the wrong color then you don't own your house.
