In much of Europe Dell will end up cheaper because it will be sold within the single market, meaning no customs tax and import levies, and warrantee doesn't cost you hundreds of Euros in shipping costs. System76 is really only an affordable option if you live in North America.

That's if this comes out in whichever European country one lives in of course, because Dell is exasperatingly vague about their specific offerings, and in my case (the XPS 13 with Ubuntu 20.04 with Dell Netherlands) I could only offer it via telephone. That part sucks. The laptop is fine though.

For the record: for my work laptop over the past ten years I've had two System76's and now a Dell XPS 13.
