Need to ground the metallic screw holes?

[Jdonalds]

I'm starting a mining rig, and I'm having issues which I've narrowed down to the motherboard. Do I need ground those holes?

Of course, that's what they are there for.

When I look at litecoin mining rig tutorials they say to use plastic standoffs... those aren't grounded... therefore those instructions are incorrect?

What type of issues could I get if those holes aren't grounded?

Make sure to use the standoffs that are usually pre-installed on your computer case. And yes, screw down the motherboard using all the screws going through the holes and into the standoffs.

Plastic standoffs? That's a new one on me. Use the standoffs that came with the case - they should be metal.

I'm using a custom case for mining. It's wide open for ventilation and the box is made from wood.

Ok, well there is nothing that requires you to ground the motherboard screw holes. I can "breadboard" a motherboard without grounding its screw holes. So the problems you may be having with the mobo shouldn't have anything to do with the screw holes being grounded. If the "case" is wood, then either metal or plastic standoffs will provide the airspace under the board needed for cooling. They won't have any grounding effect. Anyway, based on what you are describing, there shouldn't be any problems with your board related to the mounting screws and screw holes.
