Solution 2:

Personally I would recommend something like Ubuntu server, or Debian if you're comfortable with it. For a web administration interface if you need it, look at webmin.

It depends on what you want to do with it. RedHat and Debian still appear to be the gold standard, with Ubuntu the preference for desktop environment.

RedHat still seems to be the best (and in some cases, only) supported distribution rquired by CAD tool vendors. What some people do in this case is buy a couple of real RedHat licenses for reference systems, then run most of their farm with cheaper CentOS systems. If a problem is found on the CentOS system, it is duplicated on the RedHat system, where the CAD vendor will agree to support the issue.

Personally I use CentOS because most of the Linux systems I manage run CentOS.
