Thing is, it has to hold down four of those clamp terminals so any space between the head of the screw and them would be pretty disastrous.....
One more interesting bit: There was something interesting about this power brick that I didn't realize right away. I plugged it in and it worked. Normally this. wouldn't be the case without connecting a proper harness and activating the power switch and backdoor switch.
These are connected normally to a molex connector but on this one there was a plug with two jumpers to bypass this. It definitly looks factory, neatly used one white and one black wire.
So...this made me wonder if this brick had been in any cab ever at all, or maybe it was a workbench u it from the start. The almost like new condition was another indication for this.
So I asked the seller and he confirmed that all the stuff he was selling indeed came from a former workshop doing arcade repairs

That also explains the removed Big Blue I guess....
