Hello, As some of you may know, I've been interested in setting up a server for a few months. I finally got a Power Mac G4 "Digital Audio" with the following specs: Processor: 733 MHz G4 RAM: 1 GB SDRAM, and if anybody cares, at least 256 MB of that is DDR2. HDD: 1x 60 GB, 1x 40 GB, both on the stock ATA controller. SuperDrive SCSI card, USB 2.0 card. OS: 10.4.11 (non-server) So, it should work just fine. I've just got a few questions: 1. How can I setup an email server? I've looked at postfix, but the site seems amateurish. 2. How can I setup local network iChatting? 3. Where can I get a cheap, but good, SATA card? And how may drives can this take? I've heard both two and three. 4. How can I backup my computers to this? I've got two Vista Dells and the Power Mac, and a Mac mini running 10.5.7. Thanks in advance for all your help!
