Here in the EU there are a few companies selling rebranded Tongfang or Clevo barebones without an OS. Some are Linux-oriented like Tuxedo, Slimbook or LaptopmetLinux, some are general-purpose or gaming oriented like Schenker/XMG.
Slimbook Elemental 14 start at around 600€, Tuxedo Aura 14 starts at around 840€ for what looks to be the same SKU but a bit more storage.
