Yes, CentOS-3 works extremely well for server work. I've been running it for weeks now and haven't had any problems with the OS at all.
The updates seem to come out faster than Whitebox and the community appears to be much more helpful.
Whereas communication in the Whitebox community seems to center around their mailing lists, the CentOS community is online at irc.freenode.net almost constantly.
It is RHEL reborne...
