You have absolutely no part in what he does. No matter what you say, he will do what he wants to do. Your input is not wanted or needed on this subject.
If he finds that what he's doing isn't working then he'll change. But as for now, what he has is working. Until it stops doing what he requires it to do, he will keep what works. What he does affects you in no way possible. I don't believe he's running this webserver for serious use or else he'd probably put more resources into getting a desktop or something more suitable for servers. He said he doesn't use the laptop, so there's no chance of him wanting to.
So in the end it just doesn't matter. Let him do what he wants, and stop caring. You have no reason to.
