I just thought this was interesting....
"the motherboard tray can easily be installed backwards. The user manual makes no mention of which way the motherboard tray should be facing during installation so it is conceivable that the end user could get this far before realizing a mistake has been made."
but... up above when you were putting together the mounting tray
"make sure you position the motherboard tray with the D Frame logo facing away from you and set the motherboard mounting tray off to the side "
They actually did mention it.
