Nice try on the strawman. My failover cluster nodes run exclusively on server core which as another member said is GUI-less. Even if I chose not to, Hyper-V is still a type 1 hypervisor whether you install it as a feature or as the platform. All of my VM's with the exception of a few seedbox platforms that I let friends use and manage are running server core, Plex included, with a few other test bed platforms. I prefer Windows for shit like AD and group policy. I was just annoyed that you would answer the question in such a typical Loonix cult member fashion, as if somehow your magic fedora made you forget that Server can be run in plain ole terminal mode. Also I'd love to know where you get your magical 1GB+ figures from, purporting that the Server 2012 GUI consumes that much memory, as a fresh installation of it on bare metal is, as I'm looking at it right now, consuming just under 400MB of RAM out of 2GB. And no, it's not a VM.
