Did you do this for reasons of cost, tired of Microsoft operating system bullsh*t, or as a protest against Microsoft?
All of the above is also an good answer. :)
I understand the source code is available and anyone can modify it to suit themselves. I assume that's what people are doing when they set it up.
A little of all of the above. Gates is such a skanky little NWO monster. As far as modifying source code goes, perish the thought. I've been playing with linux distributions for a long time with no coding ability whatever. It's finally to the point where it installs itself and the few things you need are easy to get from package repositories or by copying and pasting scripts. Lot of info out there. Installed on a Dell Inspiron 5520 and everything worked immediately.
