Hi,

I wired my quadVCO more or less like you suggested.
I used solid wire, because I could bend it to shape and it stayed 
like that, so it's easier to maintain distances between wires and 
have more controll on overall mess. Whenever I could, I put the wires 
touching the panel, so it doesn't get messy and acts like one sided 
shield for it. All wires are soldered to connector, so PCB is easily 
removable.
I tried to route wires so they stay at least several mm from each 
other and aren't parallel where it's possible.
Power is run in star fashion. This is power for potentiometers, 
waveshapers mounted directly on switches and +/- attenuators. It was 
a lot of wires and at power connector it looks like shit.
The power socket is mounted on small PCB soldered directly to the 
panel (made of 2mm 2-sided glass-epoxy), and all power/gnd wires are 
soldered to large pads (I thought they were large before I soldered 
everything to them) coming from socket leads.
You can see it all there:
