Yes, you want your preamp case sharing power supply case AC ground. I found the frontpanel needed a good ground, otherwise the greyhills were a little static'y when touched. Also, my input transformer cases, mounting plates and shielding plates on the back of the cards (my cards are vertical) are all case grounded.
