OK, I did some poking around and it looks like a Phenom II X6 will be just fine. It seems VMware is persnickety about mobos though. Mostly issues with NICs and SATA controllers.

I see that ESXi 4.1 supports hardware fault tolerance. At work we are paying $$$ for a Marathon solution to get both hardware fault tolerance and virtualization.

So, what would you guys consider a minimum requirement for RAM?
