Cabinet hole size

[Antep]

Hi guys, just ordered a cabinet to start my journey. I'm planning to use 2 x 1 inch pipe and 1 x 1/2 inch pipe for the out flow and inflow.

How big is the hole i need to make? Is 3.1 inch x 9.9 inch enough?

Your question as stated is very confusing/lacking details..
Here is a table of pvc dimensions https://www.pvcfittingsonline.com/resource-center/pvc-pipe-dimensions-18-through-24/
That hopefully allows you to answer your own question

Note too, when dealing with pipes and hoses, there are TWO measurements, and you need to be aware which one the other guy is talking about: there is the inside measurement (how wide is the water passage) and the outside measurement (how wide is the pipe/hose itself.) Your outer measurement will affect the size of the hole you need to get it through the cabinet (make it a little loose), while the inside measurement may dictate what size nipple on the pump the hose can fit over, during setup.

I'm a fan of making whatever holes I need generously oversized. That will allow plenty of wiggle room for the pvc/elbows and any cords you'll be fishing through there as well.

When I built the stand for my 120, I solved the problem by leaving the top 8" on the back of the stand completely open. No worries that way. The plumbing can go wherever it needs to and I can easily route electrical cords as well.
