Want To Add Top Fan

[WeatherGeek]

Hey guys. My flat and closed topped NZXT Apollo Silver case currently has a 12CM fan on th eback, left side, and in the front. What I'd like to do is mod the case and put in a quiet 12CM fan on the top.
What drill materials will I need to make the hole for a 12CM fan at the top?

You'll need a hole saw, to cut the hole, but make sure it's slightly smaller than the fan.

A 4mm drill bit for the fan's screws.

And a fan
