Power supply and Clear Case

[zenroth]

Ive recently have decided to throw together a small clear case for my old lan box. My only question is its currently useing a 230watt power supply with two 110 plugins.(old style for power and monitor) Now the middle ground pin on the ac plugs, normally just screws into the power supply chassis to ground the frame, and case.

Well in this clear case I am haveing no power supply chassis, and am wondering what would be the best way to ground the middle pin?+ I know I can use the power supply fine without it, and may but im wondering if just grounding it to a metal screw in the lexan or plexi would help at all vs no grounding.

Thanks

Where the grounding wire is usually screwed down, there should be a metal contact the PCB that you could solder it to. That's how I originally planned to work mine but opted for an external solution to minimize heat.
