As far as I know is a production Laptop, a MSI Alpha 15 B5EEK/MS-158L model with
bios version "BIOS E158LAMS.10F 11/11/2024" (the newest version available at
https://de.msi.com/Laptop/Alpha-15-B5EX/support?sku_id=89840) and without 
preinstalled Windows which I bought in December 2021 at www.alternate.de (a shop
which MSI lists as a "trusted partner": https://de.msi.com/service/bzq)
