@ jojjelito: This ist how my housing looks. At the moment I'm having the sequencer right next to me so I can not measure the thickness of the frontpanel PCB. (aprox. 1mm)
These dimensions fit.
/Edit TK: this diagram is obsolete, see next page (6) for updated picture with new spacer sizes (5mm + 2x18mm)

Cool! Thanks! I need to slap a case with sides together. Otherwise, chances are that my cats will put their paws in there and do something nasty to the electronics. Otherwise it's a cool idea to do it your way
