i have two ideas for the casing.

the first is solid oak - yes i know it sounds pretty stupid (and heavy) 
but it would match the cabinet that i have all the equipment in in my 
the idea would be to route the insides out of it from behind and poke 
the keys through holes in the front. i cannot but them up against each 
other because the switches that i have have legs on their sides which 
preclude that.
so i would route 12x12mm squares in the front. might be hard work to get 
everything lined up.

the second idea is to make it out of perspex and expose the internal 
gubbins to view
sort of like the original imac. a front and back sheet of perspex 
separated by spacers with the pcb in between.

in either option the encoder(s) would fit.

anyway, this is an experiment. i'll make somethign and see how it works 
in practice.
a set of 10 encoders (on ebay from china) are costing me $16. and that 
includes the knobs.
