I'm in straya at the moment, so bit far for postage =S.
Ideally I'd like to store bootcamp externally to the egpu - looks like the HP Omen accelerator could fit the bill well. It has one TB3 port, but has space for an SSD as well. Only question is if the macbook will recognise the SSD at boot!
Oh hai. Egpu you say? I may be selling my Sonnet if you’re interested?
I’ve done a fair bit of research and had about 5 different set ups, feel free to ask any questions...
