OSX Install via Virtualbox on PC - How To?

Hey everyone,

I usually hangout in the notebook/iPad forums, but I thought I'd swing here to ask a question. As I anticipate my switch to Mac this summer (when the MBAs get refreshed), I was hoping to get a better feel for Snow Leopard (though I realize Lion will be slightly different). And while I've used Virtualbox before to install Ubuntu and the like, I've never had much luck with OSX.

I've searched these forums/Google and most tutorials seem to be out of date (from 2010 and earlier) or all about directly installing OSX to PC (OSx86 stuff). I simply want to virtualize it, to ease my transition in the upcoming months.

Any tips, hints, advice? I'm using a 2009 Sony Z (2.66GHz C2D, 4GB RAM, 320GB HDD, NVidia 9300M GS, Intel GMA 4500MHD). Thanks!

Cheers
