I’ve been using Microsoft’s Windows Server 2012 Release Candidate for my own home media/hyper-v server for several weeks now. I’ve been eagerly awaiting the final release. So far the biggest feature I’ve used is Storage Spaces. I’ve also been using Hyper-V but in a very limited capacity so I can’t comment on it too much at this point. I’ll have a full review on Windows Server 2012 probably by October.
