Hi Bryon,
I think we had concluded earlier that the ground wire connecting the PSU to the chassis was for the purpose of connecting filter capacitors between the chassis and each of the two AC input wires (hot and neutral). Therefore removing that ground wire will not create a safety hazard, but it may reduce to some degree the effectiveness with which noise entering the unit from the AC line is filtered.
With the ground wire disconnected, what you have is the two capacitors in series (the series combination having a total capacitance equal to half of the capacitance of each of the capacitors) connected between the AC hot and AC neutral wires. That will provide some degree of noise filtering, but presumably less than if the ground wire were connected.
Whether or not the difference in noise filtering might have any audible significance is not predictable with any certainty, as I'm sure you realize.
Best,
