Hi @ninja2,
I have the Minima, and it has the pads accessible on the PCB to fit a crystal and the two capacitors... although I ended up "trimming" with three per side!!!
I don't see it possible on the WiFi without a major attack - if I was doing it I would lift the two pins off the PCB and free-wire the crystal to them. But even I would rather not have to do that, and I do build free-wire prototypes with 0.50mm pitch devices!
