Tried to dremel a fan grille into my case panel, ended up with a warped mess instead

I was in my garage at 11 PM last night trying to cut a neat circle for a 140mm fan intake on my old Fractal case. The dremel bit caught on the edge and now I have a wavy oval that looks like a melted smiley face. Anyone got a trick for keeping thin steel from buckling under a cutting wheel?

Had a buddy do the same thing and @coleman.jade's kidney bean description made me spit out my coffee.

Feel your pain man... I tried something similar on an old case and ended up with a shape that looked more like a kidney bean than a circle. Thin steel just loves to warp when you put any heat or tension on it.
