The windows 8 consumer preview already has a milion downloads, I don't know how many yet downloaded the server 8 beta version but I downloaded the VHD version. It's easy to extract and then you have a vhd file which you can use to build a new virtual machine with Windows Server 8. My first impression of the setup is a bit like uhh I really don't like how they use the pictures and hope they won't use that fish during setup. You can see it as I have taken a little screenshot. I am stil seting the virtual server up but here is a screenie while it's gathering device information. I will write more on Windows 8 Server edition when I have the time to explore the server and will take loads of screenshots to share.
