I have used mini PCs as a servers for years with file serving being a major duty of them. Granted my storage needs aren’t excessive, but most NUCs or Nuc-likes can hold two drives, some can have a third if you include 2.5" drives. My AsRock A300 can hold 4 drives (two of each), but its m.2 support sucks so that’s not as much of a boon as it sounds. If you need significant storage, there is no replacement for something that can hold 3.5" drives though since those can now reach 20+ GB a drive.
Unless it is trying to actually look cool like “cool retro terminal” or something, I fail to see how the point. I don’t recall ever in the history of my terminal use ever thinking “man, this terminal emulator is so slow!” I mean, really… 120fps 4k terminals. Neat I guess?
