I got an iMac with Snow Leopard and wanted to try Snow Leopard on my PC with an Intel Quad Core processor.
I've read alot of forum-posts and guides on the internet but I'm not entire sure how to install it.

I downloaded MAC.OSX.SNOW.LEOPARD.V10.6-HOTiSO to the iMac and was wondering if I'm just gonna make a partition on my 8GB USB-memory as all the guides says and plug in in my PC and boot from the USB-memory?
And then follow the rest of the guide?

And also, is 8GB USB-memory enough?

Thanks for your help!
