Rod,

I know performance will be better, but given the learning curve, which flavor of UNIX and mod_perl would you choose for a dual P3, 1.2Mhz machine with 4GB of memory and RAID?

To be honest, we usually are deploying on managed servers, so I can't really say. For our inhouse dev and staging servers we usually use RedHat, but being that I only write the code (and configure Apache/mod_perl) my knowledge of the details of Linux/UNIX and hardware is limited. There are alot of good suggestions here already, but I would take that question over to a more Linux/UNIX/BSD oriented board and see what they say there too.
