Apart for all other cons you can think of, I don't see why a server should waist CPU cycles on a GUI and a mouse pointer.
Luckily MS has seen the light, new server versies can be installed without the GUI, commandline only.
Another point is that in linux there are a million ways to solve each problem, and most of them are well documented and/or sorted out by someone else. Windows == powershell, and I wish you good luck...
