Windows server is for servers, not for desktops.

Try it. If all your driver work then go for it. Some software that works on win8 doesn't work on win server though. they check for the OS name prior to installation.
Virtual machine
Yes, why not. There are conversion packs for that.

This attitude is a result of MS marketing. Windows Server contains all the features of a desktop edition, but they are disabled.
