Power Macintosh G4 List2/1/03 6:14 AMG4 at lists.themacintoshguy.com > I know about the fan problems (largely solved by the 4.4.8f2 firmware > update) and the audio-in hum (which I circumvent with a USB audio processor). I just purchased the discontinued DP 1ghz MDD model. It hasn't arrived yet and I am extremely worried about what I've done. I didn't see all the commotion about these possible "lemons" before I bought and I'm pretty pissed at myself for not being more thorough in my research. Anyway, I don't have a USB audio processor. I use the original MOTU 2408 with PCI card. What am I in for? I also use the sound out port of my Mac hooked up to my mixing board and thru the stereo for iTunes. Will I be able to continue in audio production with this machine? How would the hum or noise be fixed? Perhaps I should post this to the Pro Audio list as well but if anyone here has info please let me know. Thanks, Kathy
