if your not into any cutting/drilling,
I would probably say the most practical route is
Route the wires through a pci slot at the rear and stick the unit to the rear of the case (or on the side of the case at the back)
Personally I'd take the controller to bits to minimise it and drill holes for the shafts (the ones the knobs mount onto ) in the case so all you see from the outside is the knobs
Thanks for the advice Moto,
I didn't want to cut or drill 'cause I ruined a 5.25 front panel - tried to drill a circle for a rocker switch of cold cathode tubes but the panel ended up looking like a victim out of the Saw films.
I'll try to route the wires out the back like you said mate, that sounds like the easiest option. I have a windowed side panel so have to try and get it neat.
Drilling the holes for the shafts seems like the neatest outcome (depending on drilling skills) but I don't want to risk going wrong with it.
Thanks for helping.
