recommended hardware for Gigabit firewall?

[Florin Andrei]

I'm building several firewalls that need to be able to sustain 1000 Mbit 
throughput. We're using AMD64 processors a lot, so that's the kind of 
architecture I'm looking at right now. I will use OpenBSD 4.1 64 bit 
version.
The set of rules on the firewalls will be relatively small and simple. 
At least some of these firewalls will need to be redundant, connected in 
an active/standby configuration. I will need at least 6 interfaces on 
each firewall, at least 2 of them capable of gigabit speed.

What is the hardware that you recommend for this type of machines - 
especially the network cards and motherboards?

Anything that I should avoid - hardware known to have issues with this 
kind of requirements?
