Technically and realistically is not an old game. It's a remake not a remaster, the only thing similar with the old one is the story. Graphics, audio, gameplay are all new. In my opinion remakes should be able to run for goty. (remasters are different though)

Go for the second hand 1l pcs. They are better and cheaper (but less sexy) than the zimaboard. The ones with a i3-7100T should handle like 10 transcode, if 1080p. Chrapes I've seen on ebay was a prodesk 50bucks. But it's a rare deal
Yea, back in the day, when first phones and laptops were coming out, the tech was different, and was better to fully discharge/charge the battery. Nowadays it's the opposite, but the mith still survives
An easy analogy for batteries nowadays is to see them as an elastic completely relaxed at 50%. At 0% or 100% the elastic would be fully stretched. You want to avoid that to maximize its life
