case hacking/grinding advice

[Denrok]

I'm looking to do a window mod on my antec 300 and have just brought an electric multitool but what i'd like to know is what would be the best cutting disc to use? size? material? as I don't really want to make a mess of the case.

thanks

Thanks for the advice everyone, I think I will get a few discs and find some old case panels to practise on first (any donations? ha)

Typhoon what jigsaw blade did you use and have you stuck the window to the inside?
