I didn't drill any holes in the plastic. I drilled and mounted the pass-through fittings to the metal frame on the top, so the plastic covers go on like normal and hide the fittings. You gotta remove all the plastic panels to get to that part of the frame because they all lock together.
I wouldn't mount pass throughs to the plastic cover. You'd have to cut out all the metal underneath it to be able to tighten down the fittings. And the plastic is kinda thin and flimsy.
I used this step drill to drill the holes in the metal frame. A step drill is the easiest way to get clean holes that size (20mm).
edit: if you want holes in the cover just for easy access I'd still use a step drill. A regular drill bit that size would leave some shitty looking holes. A holesaw might work good too.
