An suitable motherboard and an intel 82599 based ethernet card ?

The latter will set you back approx $700, but $1000 should get you far
in total.

The 82599 has some very interesting time-nuts features with respect
to the GPIO pins.  Unfortunately I have not been able to find out if
these pins are accessible on the Intel ethernet cards.

Never attribute to malice what can adequately be explained by incompetence.
