Intel Ethernet Converged Network Adapter X520-DA2
Value & Price Guide
Got this Intel X520-DA2 dual port 10Gb network card for sale. It's a solid server-grade NIC with two SFP+ slots, perfect if you're trying to upgrade your home lab or server to 10 gig speeds. It uses the Intel 82599 controller which is pretty much the gold standard for compatibility with stuff like pfSense, TrueNAS, or Windows Server. Pulled it from a working machine, looks clean and has the standard full-height bracket attached. No transceivers included, just the card itself.
