Q: Mountain Mods IO panel depth

[alaricljs]

I'm asking here since MM has yet to respond to a single email I've sent (it's been many weeks)

Does anyone know the depth of the MM IO Panel? That would be the distance from the mounting surface to the inner surface where motherboard is mounted against it.

Thanks in advance!

edit: Possibly an easier to understand description of what distance I am looking for. Draw the smallest box that could contain the entire panel, I need the measure of the shortest side.
