Windows 8 on new PC build?

Hi guys, I'm going to be building a new PC soon, and I'm trying to save as much money as I can for the parts themselves.

I was wanting to know if it is possible to use the Windows 8 release preview as the first install on my new PC from the BIOS. This would save me $100 over buying the old Windows 7.

I just got Win7 for my new pc. It has a free Win8 upgrade i can ( and will ) upgrade to when it comes out. 8 supposedly idles at 500mb of ram stock. And that is... beautiful.

too bad 16 GB of ram only costs like 60 bucks.

That would have been useful when vista was released.
