Shame I have a spare 4 octave keyboard you could have had for a 
tenner+postage, no contacts though.

You have to first decide what you want... do you want it patchable?
Which mmodule has the most knobs/switchs? (usually the VCO)
Also decide what sized pots/switches you're going to use.. its no good going 
small panels if you gonna use huge pots and wafer switches.

I use a standard 3" by 9", it has 8 holes for pots/switches and 4 holes top, 
4 holes at bottom and 6 down the sides for sockets/led's.
I use this as the basic layout, some of my modules require custom panels 
(PPG VCO, cause it has led display) and the multijack are good examples... 
but they all have the knobs spaced the same as are the sockets... this gives 
a nice looking bank of knobs/sockets... take a look at my web page, in the 
'Piccys' section. Mine is the Blue one..
Its bigger now as Ive added a quad EG and Quad LFO, I also put it in a 
bigget case, two rows of 10 modules, though its not yet full..
