You can request a specific machine to be flashed and sold by contacting me over email. If you are not buying with crypto, I will create a private Stripe listing for this machine so that you have the same buyer protection as when you are buying from a public listing.
Payments will be made upfront as I often have to buy computers and parts for them; Unfortunately I don't have every Libreboot-compatible machine on hand.
Please verify that the machine is compatible with your boot firmware of choice by visiting its hardware compatibility page: [Libreboot] [Coreboot] [Canoeboot]
