Here is an idea I had, but yet to try. A pointed "spear" of sorts, think of a putty knife? but pointed?
The metal then could be bent in, it wont hurt anything to be inside the can and adds to thermal mass.
I am under the impression that depending on how many rows of cans you have and length, that airflow restriction is not an issue unless your your panel just doesn't move enough air..
It be interesting to do a flow test on various openings.
If you want a large hole in the bottem use a 11/16 hole saw. It will fit on the inside rim of the can. If that a little confusing take a pop can to your local hardware store and try different size hole saw till you find the size that works for you. Hope that helps. Dan

"Just do it" is a good way to start
Rock on

WOW!! That one got chewed up a little. :)
I used a manual opener. The cutting blade rides around the inner rim of the can.
When you first bite down on the edge, you should hear it click through.
I hope this helps, but I'll be sure to include it when I build my second panel.
Good luck...
