Don't see why not, I am. Under load, linear PS lower thier voltage, but thats why you give yourself a few volts headroom.
That is a dual PS, 17.5V(No load) 40Amps mounted atop my tower case. also, those capacitors are overkill and the ones you would normally use have much smaller dimensions.
As for mounting, I just like mounting the components to the top or floor of the case, but I can get plastic or aluminum boxes too.
meters and LEDs are extra too of course.
