The cheap way to get nice results is the Raspberry Pi for $40 (Amazon) and the Allo DigiOne (Allo in India) for $100 and a SD card for $10. It’s a 2-board stack with connectors. You can put it in a box, or not. They make lots of plastic boxes for this.
There are lots of instructions online to load the OS, DietPi onto the board and program the board from any computer on the network using an app called PuTTY. Google these. All free downloads. You don’t have to be a programmer to do this.
This will give you BNC and RCA outputs to your DAC. You can load DLNA driver from DietPi and Roon Bridge. Then you can use Roon, Jriver or Audirvana + to send music files to it.
The result is quite good, although not quite as musical as my outboard Ethernet renderer which costs $3K. How can you lose for $150?
