Well, alright. I can see that this isn't possible in the way that I've thought that it was. I was thinking modding the case to accommodate 2 17" Macbook Pro batteries would be enough, but deep cycle marine batteries? Yeah, can't do that.

Well, thanks. I'll be sure to post my touch mod and what all I'll be doing with it here when it's done. I'll be getting the touch screen component some time in September, so it'll be a while, but the end result should be pretty badass. laugh

Thanks all for the help! laugh
