There's still time to get people in your server - I'm just now installing Windows.
So far, the installation has gone quite well! Everything is detected, I got POST on first boot, so I'm happy.
Server OS's usually take a good deal of time to load, and even longer to configure. I'm estimating another 30 minutes to install, and 45 minutes to configure. It shouldn't take me too long after that to get the Minecraft service itself up and running, and I can work on installing the other items a little later (though I'll probably have to restart the server again a couple of times).
