At the end, I went for a Lenovo V330 on sale since I couldn't justify the price of System76 plus shipping outside the US at the time.
Disclaimer: I'm not affiliated with System76 in any way and have never owned a System76 laptop.
Their hardware, though, seems to be meh. Give me this on some high quality hardware.
I've been debating hackintoshing it (https://github.com/Errrneist/Hackintosh-Thinkpad-X1-Extreme) but it seems like eGPU support isn't there and that's one of the primary use cases I got for this laptop (CAD primarily).
