For example I don’t know if a cheap mini PC like the GMKtec G5 would be more likely to have firmware/driver related security flaws over a more standard PC like an older Dell Optiplex from Staples.
Maybe there is something else entirely I am overlooking. I’m not sure. Most of the complaints I’ve heard are in regards to mini PCs containing bloat and potentially malicious things installed.
I doubt it’d have anything malicious in the firmware. I’d be more concerned about getting ripped off with fake parts or having it break on you.
