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.
I’ve taken to using window air conditioner filter material on all my boxes. Cut it to fit the intake and even taping over other intakes to ensure the air path is through the filter.
I hold it to the case with small neodymkum magnets. Once a month I rinse it out and put it back on. Case stays much cleaner inside.
That’s still easy enough to get at most home hardware stores.
