Another quick note the board has a stock backplane.
I did not remove the backplane or install the plastic backplane that is included with the Thermalright Assassin cooler. I just used the specified Intel spacers and included screws in the package.
I am fairly confident that the low profile cpu coolers with spring mounted pins won’t work with the stock backplane. As fair as I Know, generally you SHOULD NOT remove the stock backplane on a motherboard like this. So keep that in mind when looking at parts if you are using this board.
