Hardware components of Librem 13 Version 4

Hi, where can I find the exact hardware components (all items) that consist of the laptop Librem 13 version 4? Do I need to send an email to someone with the serial number or are all hardware components standard for this model?

Pls advise - thank you so much

Kind regards,

I would suggest writing Purism directly anyway, as that is the only way to get official information by default.
