i will post a picture later today.of the tower in question.
here is the tower,you might not be able to make out much.
but there is only about 25mm between the busboard and the motherboard under it.
and the busboard sits on top of the keyboard interface just like most busboards.
you can probably make out where it will/might foul on something else because of the rj45 connectors.and riser board.
its pretty packed under there
,i can't use a indi as the fastata is in the way.
