Maybe one way to start working on the freedombox with this plug you
received might be to install debian on it, with encrypted rootfs, and then
install a bunch of the software/services listed on the wiki, with minimal
configuration and try to benchmark it to see how it behaves.

That would help to have an idea if this kind of hardware is able to handle
the load and then define the hardware requirement a bit better.
