It does not come with a SPDIF bracket. You can use COAX SPDIF but not optical. I have 3 different brackets and optical will not work on any of them. I made a new bracket with only optical connector and got it to work for a short while but it stopped working. The board still puts out +5v on the SPDIF output but no go.
Foxconn sent me their SPDIF bracket and it only has COAX on it.
