Each of the corner mounting holes is surrounded by signal ground. Put=20
a ring terminal under one of the corner bolts and connect the cable=20
shield to that.
Then, if you want to try an additional Earth ground to the system,=20
connect it to that same point. But that node must also connect to the=20
computer signal ground, and to the case and power line safety ground=20
line. So adding an additional Earth connection risks a ground loop.
