Im really leaning on used sfp+ cards with a DAC. It'll be a nas primarily. (Unraid) Only 2 puters in the loop. Im planning on p2p to get rid of the 10GB switch that I dont need.
Asrock Rack intel c236 chipset......dedicated ipmi lan port:) BMC
32 GB ECC Udimms (2x16)
Xeon e3-1225 v5 (onboard graphics)
........and a Win10 Home machine attached to the other end.
 
I think @lowfat has done Mellanox InfiniBand before, might be another option since you're just doing direct connections between the 2 devices.

Used hardware is the most cost-friendly approach to 10G. You should be able to find Intel X520 cards for roughly $50 as an example. Whether necessary or not, I glued 40mm Noctua fans onto mine as I don't have the traditional rack airflow that they were made for.

Yeah used is the way IMO. ConnectX-3 cards are in the price bracket as well*. Depending on the price of the DAC (and length needed), sometimes cheap used transceivers and optical cables from a place like www.fs.com may be cheaper (they are great anyways if you need anything fiber).

I haven't looked in ages though, lots more cheap mainstream companies these days (10GTek etc)

* edit: should add, depending on the model, the ConnectX-3 (and later) cards are 40 gbe capable if they have QSFP ports (and faster if you want to mess with IB).
