Good laptop for whonix

My laptop is broken. So I want good laptop for whonix.
I’m thinking Thinkpad T400s , Pinebook and Librem13.
If you know something better one, could you tell me? I would be very glad.

What laptop have you used and why?

Thank you for reading.

Whonix can work on any budget machine that supports Linux or even Windows if you are hesitant about switching for some reason.

No need to go overboard unless you really want to support these open hardware projects, Note that a totally libre x86 machine is pipedream if you are a purist. Might as well go with OpenPOWER instead.
