Firestudio Project underside screws

I'm hoping to confirm that the underside of the Presonus Firestudio has screws or some kind of grounding/fastener that connects to through-holes on the PCB. Mine has several empty holes and a light imprint of what looks like a grounding washer. The PCB has holes that line up.

I picked it up used, and it seems to be working well. I did notice during light repairs that the unit is comically sensitive to grounding issues. Just nudging the PCB was doing all kinds of crazy stuff when I had it taken apart and plugged in.

So, it's working now, but I'd like to have all the grounding/fasting that the unit needs. Can't really find any pictures online of the underside, and the machine-screws used on the rest of the chassis don't seem to fit.

If someone wouldn't mind taking a look at the bottom exterior of their Firestudio Project I'd appreciate it very much.
