I was wondering when people consider themselves to have a new PC. Technically I’ve had the same PC for close to 20 years now, but every part’s been upgraded several times over.
I figure everyone’s got a different mind about it. For me, I’d have to say when all of the big three—CPU, GPU, mobo—have completed a phase, my brain thinks of the previous setup as “the old PC”.
Not if you have pets. You’ll need a screen to stop hair getting into the case if you have cats/dogs.
That’s still easy enough to get at most home hardware stores.
