Cheap 2x NIC OpenBSD device

[Alex Waite]

I'm deploying a server to a different data center and I don't want to 
expose the IPMI interface of the machine to their semi-trusted 
management network. So, I'm planning on putting a simple OpenBSD device 
in front of it, logging and filtering.

Can someone here recommend a relatively cheap (< ~100 EUR) device that 
runs OpenBSD and has 2 NICs?
