I'm looking to run an enterprise setup at home for the purpose of learning. I'm somewhat familiar with Windows enterprise systems as that's what we use at work. But I realize that I'm at the beginning of my IT career and Linux is the choice of many larger companies. I think it's smart to become familiar with the Linux side of enterprise and I figured setting up a small setup at home with my computers made sense.
I need it to be free, there's just no room in the budget for this (so that rules out REHL I believe). So it's a toss up between CentOS, Debian, and maybe something I'm missing. What's my best bet?
