I'm getting the DAC2 Pro for a build for a non-audiophile friend as a gift, who nevertheless is very much into the Raspberry Pi. I was thinking a Pi 3B might be good enough but wanted to check about software system requirements and recommendations, as well as case. I would have liked to get a nice metal case but it seems that would mean going with a Pi 4B with higher cost and I don't know that's even necessary unless it's someone who may need the expandability like if you want to add DSP later. Thanks for any advice.
Build recommendation for DAC2 Pro please
