Advice? Drilled Tank Question

Wanted to get your guys opinion on what I was thinking before I placed my order. I am looking at drilling a 72 bow on the back top. Looking at using two 2" bulkheads (overkill I know, but I thought I read that the less flow going through the quieter they are). Then would T the line and drill a small hole in the pipe cap. My return will go over the tank (not drilling). Also thinking of using the following overflow box and bulkhead strainer:

The tank is near our bedrooms and living room where we watch TV so I want to make sure that it is relatively quiet. Doesn't have to be perfect, but no gurgling. I saw the Bearnie and Beananimal, but didn't want to make that complicated. Looking for simple, yet effective.

Thoughts?

 

I saw those guys. Looked good, but saw mixed reviews on noise. Do you have any experience using them?
