I recently bought a Dell CS24 SC Server to use as a gaming server. I installed Windows Server 2012 R2 and started running a Minecraft server on it. I liked the OS and decided to go look for a license key to buy it. Only to be met with a myriad of strange terms and different types of licenses, like user CALs and something about buying a license for each processor. I am but a simple desktop gamer, and I still need to head off to college to learn about servers. So my question is, how the heck am I supposed to buy this OS? And furthermore, SHOULD I buy it, or look for a different OS?
