How familiar are you with torrents? I can send you an invite to a private tracker full of 4k remux documentaries… I just think you are better with 1080p if watching on a laptop. For me at least, I can’t tell the difference (and I have a 4k screen on my laptop)

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

Do you have a secondary monitor? How do you handle sleep? Using laptop? How do you close your lid and get everything to hibernate/sleep? Those are my biggest gripes right now
