Technically any x86 PC with the ability to have two separate Ethernet ports would work, but unless you plan on grabbing a NetPC from the 2000s/2010s (which will have dogshit processors and probably no expansion slots for the second Ethernet port), you might be out of luck.
Although if there is an ARM based version of the software (or if you could run it through a compatibility layer like FEX somehow), there’s tons of low power devices that could be repurposed.
