Openwrt generally works great on x64 PCs. Thiss machine will most likely be more beefy than your home router and could become your main firewall. It can handle adblocking and vpn client for all PCs on the network as well or whatever your need, as openwrt can do many nice things no commercial router can do out of the box. Install openwrt on your home router as well and use that as access point (connected via cable). You will improve your wifi signal as well. If your machine does not come with rj45 lan ports, install usb3 to rj45 adapters to the usb3.0 ports. They will give you the full 1000 mbit speeds.
I’ve been with 1984.is for a couple of years now. I think my domains cost around 12 Euros a year each. Their web GUI works fine and I’ve never needed to contact their customer service, so I cannot comment on that.
