I have a new 1 inch bi-metal holesaw. I also bought a round file to finish off the mess I'll make.

Other than that, the only experience I have was on old throw away cheap steel cases, and I made an oval hole in one and a jagged edge hole on the other that looked like a hole saw lol

I'm sure aluminum is easier to work with, but skill and experience is an issue.

The mitigating factor is that the mobo sits on top of any mess I would potentially make anyway.

Thanks. I need the luck.
1" holesaw is cake if you use the wood both sides.
Virtually eliminates tearout and the need for filing after.
I've heard that trick of running the drill backwards but never done it as it should dull the bit by doing so..I think..
Wood both sides, 90 degrees to the material, med speed and your golden.
