There are no real requirements for hardware or network, though of course
the bigger the better. You should count on about 1.5 cores being
consumed by tor and obfs4proxy, so a two-core machine may struggle
(bridge operators: does that match your experience?).

Here are some of the existing default bridges; you can see from their
bandwidth graphs that they tend to read/write 5–30 MB/s:

As for geographic preferences, I don't know.
