What is the height of the IVY III/Buffalo II stacked combo, not including the lower IVY III standoffs, and how many mm could I shave off by reducing the standoff height (and the pin length) between them?

I know the heatsink height of the placid power supplies may be the determining factor, but I have them already and can measure them. (and could also sink them to the case if needed).

Also, I know keeping the power supplies close is important to keep the PS impedance down, but could the transformers be put in a separate case(with a 1 Metre umbilical)? (I don't see why not myself)

While waiting for my Buffalo II to be delivered, I'm trying to work out casing options.

Thanks
