AK,

this is part of the problem i've been having. the width and depth would be fine but 2 inches just isn't high enough to fit the inductors / caps that i'd like to have in the improved version. the box would ideally be about 350x350x200 mmthis would allow me to have room for decent internal paritioning, shielding, big caps and inductors and hefty wires. as well as decent connectors on the outside.

cheers
