I run a farm that includes many Dell servers, but they're all at least a year old, and besides I put Linux on 'em. Good hardware, I must say that.
But pre-installing a self-signed root cert on a consumer machine? That's not even a "rookie" error. That's just "too stupid to be let outdoors".
Like someone else said, "That's so out-of-this-world stupid, it doesn't even rise to the level of 'wrong'!"
Yup, good hardware. And a data center won’t get metal with pre-installed OSs.
