Build an AMD processor computer. Add a Pink Faun card of your choice (USB / SPDIF / I2S). Then get a dedicated linear power supply for the Pink Faun (such as Farad Super 3 or Teddy Pardo or some others).
I would recommend using a higher end power supply such as Seasonic or similar to get the least amount of noise. You are pretty much stuck with switching power supplies in a computer unless you try to build a small format music server (there are linear power supplies out there that support PC motherboards).
