How to cut wooden box to install cooling fan
I was thinking to install https://www.amazon.ca/dp/B00QFWLGPU?ref ... _122623040 this fan on those boxes. Now the question is that how can i cut a square shape hole (matching this fan) into the box which are attached to the wall. I own almost no tools and don't have much experience on these kind of things. So any help would be appreciated.
