I'm conflicted... I need a new web/mail server -- my 1.2GHz/1GB G4 Cube is no longer cutting it. I have a line on a G5 dual 2.0GHz Xserve (2GB/2x80GB) for the same price as a new C2D 2.0GHz Mac Mini (which I'd modify to use an eSATA drive enclosure). Other than a vanilla OS X Server 10.5 install, primary drain on the system are the primary image/PHP libraries (GD, ImageMagik, etc). The server has a relatively light user base. Any insight/advice? Thanks!
