I ordered the SSI EEB version of this board, and it came as requested.
The tray complies with the current standard.
Unfortunately my motherboard, ASUS Z10PE-D8 WS, has a combination of current and legacy mounts, specifically, H' Y' and J'.
So as is, my mobo bows a bit in the center. That is the only reason that I gave it 4 out of 5 stars. Otherwise this tray is really well built.
