simple freebsd router for home use

[Martin Cermak]

Hello guys;

I am not a member of this list.  I only have a one-shot question
for you: I think of creating a simple router for home use with
FreeBSD. Just for fun.  I imagine a single printed circuit board
with passive cooling, with 3+ 100+ Mbit/s ethernet ports.
Preferably an open source hardware.

Can someone give me an advice wrt which HW to buy so that it will
happily run some of the recent FreeBSD releases?

Thanks,
Martin
