Raspberry Pi alternative for WireGuard VPN

I need redundant VPN access to my server. What alternatives to the Raspberry Pi are there that can run Wireguard VPN? If a regular Raspberry Pi would actually be better, that’s fine too.

Requirements:

  • cheap
  • available now
  • preferably 1 GbE ethernet though would be happy to look at lower priced 100 Mbps options too.
