If you make hardware, you test and sign the driver. Here is the doc:

"Over time, we expect to see better support for the X553 NIC. The major competition for this unit will be when the higher core count variants come out and iterations that support 10GbE."

Yep, I'd completely agree. The current one is a great low power system for backups and what not, a low end XEON could make these a great box for home lab work.

Yes, after a decade of trying to buy these, suddenly the low power, low cost SBC market has exploded. Now you can get x86, AMD64, MIPS, ARM32, ARM64, FreeScale and more for cheap!

If this had 2 ethernet ports could this be used for something like PFSense?

Yes, it is just a normal PC.

But it only has one.
