How to measure for pass through fitting in my scenario?

Hey guys, just finishing up my case for the custom loop and I have encountered a problem. As seen in the pictures, https://imgur.com/a/tf8U7, I need to drill a 20mm hole to fit my pass through fitting in the PSU shroud. The problem is, however, I am not sure how to accurately do this and get it right. I am waiting on a different T block before actually fitting the drainage system to the pump top and then I can see where I will need the hole to roughly be.

Has anyone got any tips since I don't want to end up with a hole in the wrong place, lol.

Are you able to see the fitting when you hold it beneath the shroud, and look down onto the shroud from the outside of it? If yes you can see where the fitting is.
Yeah, I think half of the fitting will be visible and half will be covered. What would you say I do to mark the drilling point though?

Right, when installed you can see the top portion of the pass-through.

What I meant is you could hold the fitting beneath the mesh and see it through the holes and that way you mark up where it's going to be, and drill there.

That's assuming you can see the fitting through the mesh.

You have some wiggle room built in to the locking collar. You don't have to be laser perfect. I would pull the locking collar off and put you assembly back together. The locking collar OD is the same as the OD of the pass though. If you can see enough of the pass thought flange, lay to locking collar over the top of it where you want to drill. So you have pass through, metal and then locking collar. Line up the outside edges. You should be able to mark out the ID of the locking collar. Once you have the inside marked out. You should be able to find the center. Drill pilot hole, then drill 22mm hole. It should line up enough to work.

Thanks for your reply. I actually have drilled the hole now and it seems to be fine. https://imgur.com/a/wnMuq

I could drill it a little bit bigger to I can move the fitting to the right to straighten everything up. However, the pass through doesn't seem to be flush with the shroud? Is that a problem?
