How can I send and receive audio from a between different computer across the internet?

How can I take the mic input from one computer and send it to the server, then have it act as the mic input of a Windows server.

Then have the server’s speaker output send it back to my computer, for it to be accepted as mic input so it can be processed for streaming/recording?

For context, I am working on trying work around the fact I want to do some audio processing for streaming, but the issues is that the application requires a graphic card. Already looked into adding a graphic card to my computer and blocked by the OEM’s decision to use proprietary power cables in my computer. At the moment, getting a new computer that is powerful enough is too much for my shoestring budget. However I realized I could rent a server that does have the processing power for a fraction of the monthly bill needed for a new computer.
