I've got an Asus TUF Gryphon Z87 MicroATX board I can part with. It's been sitting in its box in my closet for a couple years. It would come with the board itself, the backplane, the thermistors, and the Q-Connector (no Armor Kit).
I can't promise it works, and I have no CPU to test with, but it worked perfectly the day I retired it.
