Thank you for you answers. In the thread I can see that someone has made it work with 16 Gb RAM. RAM is not a problem. I have found a PC with Windows 8.1 pro with 32 Gb RAM. But has anyone made it work on Windows 8.1 Pro because I only see Windows server 2008 R2 and Windows server 2012 in the description on partnersource.but I also have a mail from Microsoft saying that it should be Hyper-V on Windows 8.1 or Windows server 2012.
I want to use this as a PC for other private things also so I would like to make it work with Hyper-V on Windows 8.1 pro but it would be good to know that others has succeeded with this.
