Welcome to the group! I've got a Cube 1.4ghz with a Geforce 2MX and Apple 15" LCD, 512mb RAM (need more), 120gb Seagate Barracuda HD 7200rpm and very quiet, same internal DVD but never use it. I'm also using an external 80gb HD, External Pioneer DVD±RW and a MOTU 828 firewire audio interface. I've tried Tiger, but then downgraded to 10.3.9 because I found it made some programs freeze and I had the twirling ball a few times, so I might wait till I go back to Tiger! Good luck! Alex
