Right now all units are on separate rolling carts and having a problem seeing 4 different ground wires running to a main on the wall. Hope you get the idea of what I'm saying
All you need is some 10-12 gauge stranded wire such as used for automotive at this point. A clip on the wire would make it easy to hook up. It should be run to a metal pipe or some other piece that goes directly in the ground.

As far as the ground needing to be shorter than the ground to the path...Don't worry...it will be. By the time it goes back to the panel and finds multiple paths to travel down it will be. Electricity doesn't just follow the shortest path. Think of having a splitter valve open on your water faucet. Then think of having both open with one having a 10 foot hose and another having a 20 foot hose. The water will eventually come out both hoses...more out of one to be sure, but it will still drain out of both. That's what happens with this sort of ground. You won't eliminate all HF, but you will greatly help. The shorter the wire, the better of course. But in our case of the example, if the 10 foot hose is the main ground that feeds back into the box then there are a dozen more hoses attached, as the ground ties into the box, it can back feed into other outlets. This is why it is important for computers to be electrically protected... and why when lightening strikes it gets some items and not others, although all may have received a jolt.
