Beginner question about building a mining rig

[Rooaraak]

hello, I'm starting to build mining rigs myself, I know how to connect everything and to work with BIOS but I would have some beginner questions:

1. Do I need to set the grounding for the rack that I'm putting the components on and if yes how do you do it?

2. I have metal racks that I will build my rig on so what do you put under the components so they are not in touch with the metal or is this not a problem and you just put them directly on.

3. What are the most optimal setting for GTX 1070 ti and GTX 1080 ti that you use in afterburner (memory clock, core clock, power usage...) so they run optimally.

4. Any other tips and tricks and situation that I should be aware of?

Thank you for you answerers.

I assume that the sockets in your walls are grounded.

Then your psus Will be grounded and the  components connected to them.

Others correct me if im wrong.

As for  overclocking  just go to https://whattomine.com  and your Will see what settings for your gpus.

As for spacers there are mobo spacers that your cancer buy preety much everywere.

But myself i just use these type.

Be aware on whattomine the numbers are often greater than you will achieve.

My 1070 Ti setting are 80 / 200/ 700
