OrangePi Zero connector case mod

data

I need to attach some devices via spi and i2c to an orange pi zero but would like to keep it in its original case.
Just soldering a few wires to the gpio pins and drilling a hole in the case isn't really an option. I am looking for
a nice and clean way.  Browsing through AliExpress looking for connectors has not revealed any suitable options
so far. I already thought about adding an 2.54mm 2x26 Pin Male Double Row Right Angle Pin Header and
cut a suitable hole to the case but I guess it would protrude too much.

Which connector do you recommend? It should have at least 4 contacts.

Has anyone modified the case and added some small connectors? Photos?

Looking for your suggestions
