Thanks for the wifi tip, probably useful on the go (provided I secure it
properly). Otherwise, if it's mostly at home, I can plug it through ethernet
to my router I guess.
I'd definitely try to stay away from flash memory. I suppose I can install
the OS and the data on an external HDD.
The CPU is indeed the weak spot. Ideally though, the bare minimum would be a
mail server, some sort of search engine (maybe searx, but I need to make
calculations regarding potential CPU ressources used on average), and OpenVPN
or something similar.
The other services would be great too, but definitely not as essential.
Would you say that these 3 services would be too much for the CPU to handle
decently?
