I have an early Pete Hand FLW clock, to which I added the PIR sensor. It's actually positioned outside the acrylic case, along side the feet. Very inconspicuous. Since it's essentially black in color, you will not notice it until you look for it. I don't even think it's visible in this picture:

Drilling a hole would have made it very conspicuous. It does seem to activate the clock from about 20 feet away.
