What is all over my head, but leaning to maybe not going to the appointment, see. JUst buying new...

Diagnostic not come up as I said, any idea of that? Bad sign? Hold down D on reboot, no diagnostic.

1 TB, good only $200 more, concur.

$100 more for 10gb ethernet? I do used dedicated corded ethernet, not sure what 27 " is right now bringing in. My guess is 5 GB is fine?
