Computers are DISPOSABLE!

You get a few years out of them, then they are put in the closet or tossed out. Nothing is sadder than an old machine. They literally WON'T be useable after a while. Sure, they may still boot, but you won't want to do any real work on any consumer machine older than about 5 years, let alone 10 years. Laptop batteries wear out and a new one is as much as the replacement value of the machine after 3 years. Sure, if I think real hard and pull out a nose hair I may tear up about that old 12 MHz 286 with an amber monitor that was my first PC but no way would I try to keep something like that alive, let alone work on it.

Get a bike. I have a 20 year old bike that I've ridden the crap out of. Still works. Still as fun as ever. Still can get parts for it. Still love it.

Get the bare minimum computing hardware you can get away with and spend the rest on something that will give you everlasting joy.
