If it doesn't need to be portable, that's certainly a good way to go. Note that the Allo Boss2 gets you everything except an amplifier and speakers, incluyding a Pi4, assembled, in a nice case, for $185. You might like to run Owntone (formerly forked-daapd) on whatever machine holds your storage - or anything else; the Pi can mount your storage via NFS or CIFS or basically anything else.
