The worst laptop you can find could probably be better than even a reasonably specced VPS. Low end VPS are dire, and you can get some pretty decent laptops for almost nothing. If it’s pre 8th Gen. Intel they’re basically worthless on the used market. But they’ll still easily get the job done.
I think their confusion comes from OPs title.
Why is it “e-waste go brrrrrrr” when OP is presumably saying they’re keeping this laptop out of the machine? _ machine go brr is a dumb meme in the first place, people using it the wrong way makes it even dumberer.
