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.
Probably about the same, you still have stuff like the intel management engine backdoor.
