@coldfuture - at the moment i've just got them sitting on two layers of foam (abt 6cm high) that comes with the case. I had velcro hooks already on the bottom of the MD and MnM but it won't grip onto the foam. yeah I might velcro the front/side edges of the elektrons to add some more stability, it will work fine for the MD and MnM but for the OT there is a small nub which protrudes about 4mm on the inside centre of the case, i think its a pressure equalisation valve or something. worst case I can velcro the MD/MnM to the side of the case and then the OT to the MD and MnM. even without velcro i think once everything is in there it should all be pretty snug and shouldn't move around much.
There is a third layer of foam which i might use to cut out some small pieces for extra padding in between boxes as well. The lid also has a layer of that dimpled foam (similar to sound insulation) so that should also keep things from moving around i hope and also give some protection for the knobs.
i'll post another pic once i've got it all cabled up properly and with the powerboard inside!
