Beelink and Minisforum are legit
I wish I knew a lot of this when I first started shopping for a mini PC. I ended up with a Beelink model that I’m quite happy with, but it seems almost luck that I didn’t pick another one, and I would have liked a “reputable brand” search function.
I see Mint as the more reasonable option that keeps 98% of the advantages of Ubuntu, with less of the crazy. I was a xubuntu user a decade ago, but have been very happy with Mint xfce since I switched.
