Adding extra grounding cable to computer

I suddenly has an idea of adding grounding cable from my casing to metal frame of my computer table which has metal feets.
This extra grounding should help in preventing electrostatic current and white noise cause by components/electricity/electric field.
It's a sucess for my and maybe i will upload a photo of it. I also provide link on sale of grounding cable and grounding information
for your reading pleasure. Kindly share your opinions. 

Update: Photo of my computer with newly make grounding cable. Kindly give opinions.
