Once the knob removed, you won't have to worry about someone messing around with the thing.
But then again....you won't have an awesome blue knob with a Matheson sticker on the cap.
good to try, but is there any need to make the system stationary underneath your fish tank, if your fish tank is not an oversize one?
besides front bracket panel mount in your picture, there are back bracket mount or back support mount(mainly for single stage), and manifold back support mount.
swagelok compression tube fittings and swagelok braided air hose, or parker parflex hose, are good to connect between the regulator and co2 tank. These high pressure hose or fittings are quit expensive, anyway, you can get a $500+ matheson 3120 regulator for $100, look hard enough you will find yourself the right braided hose and compression fitting at really low cost.
this is one of the typical mounting spare set(manifold back support mount), I've showed it here or there, and actually it is a set I save for myself, once the new stand for the fish tank is built, this mount set will be utilized. several other back bracket mount kits available though, don't have the picture.
