I'm glad you are making progress!
I'll try to spend some time this weekend trying to substitute my ER-Lite with OpnSense. I need to check how to do the iperf test -I'm not familiar with it.
I will be interested to see how the 2 builds compare -mainly around the 2 nics: expensive route vs dirty cheap :)

yes i am not sure this old optiplex is even worth the $100 of network upgrades.  but i am hoping the dual nics and intel chips will be useful later. 

the iperf setup was surprisingly easy using this brew method between two macs (https://www.macobserver.com/tmo/answers/how-to-test-speed-home-network-iperf) .. i was using a few weeks to test the NAT throughput of a tp-link 'business class' router .. advertised as 800Mbps .. but actually doing only 600Mbps.

so now i have two more ethernet ports to work with.  the mini pcie extension from adt-link works very well with the jetway/intel card.  at some point i will try to mount the cards inside the chassis.  if anyone else tries this, i would recommend longer than 15cm extension.  maybe 30cm or more so you can mount the full size mini pcie card at the back.  there isn't enough space at the front unless you remove the usb and audio card.

extension cable fits barely above the speaker mount.
