My notebook only has 8Gb of RAM, but otherwise is quite fine.
With #kicad 10 around the corner those 8Gb are not enough for a browser and kicad at the same time, so I am considering of upgrading the memory. But its soldered down.
The fun part is that @gregdavill made a blogpost about that. And my XPS13 seems to be quite similar - I already checked the schematic.

I will need some board to practice first though before I even consider buying new chips.
