What does DI-ing mean?
DI: Direct Input. Either if the soundcard and such allow it by simply inserting the guitar (or whatever) into the Audio interface, or through a DI-box that will transform the sound into something that resembles the output of microphones and connecting that to the Audio input.
 
Well, iMacs that come with the Seagate drives are louder, but better, they use perpendicular recording making it VERY fast, my seagate hd is much faster than my friends imac with the same specs but with a WD HD. I think his is a tad quieter, but who cares, its faster, and it depends, his house is really noisy, mine is almost quiet, so i can REALLY hear it well. Whats even worse is my Western Digital 500GB MyBook Studio Edition external Hard Disk Drive, that thing crunches, i had to lock it up in a cabinet next to my imac, literally, and every single time it wakes from sleep it makes a buzz.

Works great with my Podx3 but, you can't do that with a microphone. The mic pics up any ambient noise, especially condensers mics.
 
My iMac is really really quiet. Even under stress, it's still virtually silent. One time, for no reason that I could see, I could hear the fans whirring, but I just closed all open programs and then it was quiet again. Much quieter than my G4 iMac.
As far as external drives go, well don't know about any really quiet ones. I have two external drives and they crunch and whir away.
Anyway, another "very quiet" vote.

I was wondering if any of your guys could post your opinions on how loud/quiet the new Alum iMacs are. The reason I ask is because I record music, and don't have a seperate control room so I need everything to be SILENT. I have a C2D MBP right now because it is dead silent, but I must admit that the new iMacs are tempting me. Do you think they are quiet enough to record music with in the same room?

I have never heard a peep out of my iMac...this thing might as well be turned off
 
How funny to see this post. I an Aluminum iMac at work and today I kept putting my hear to it to hear it and nothing! I had to copy some things from a DVD and even the optical drive is nearly silent. Very nice design Apple!
 
Rig for silent running...

And no pings.. this is by far the quietest device I've ever owned. Even under a load of 7 different applications earlier today at one time. I'm loving it more each day.
 
no sound

completely silent for my imac 2.4 24 inch.

even my extenal hd with no fan makes more noise.
 
mine is pretty quite...i can't hear it at all over my wd mybook external drive that i use for TM.

Correct. DI only works for non-miced (non-miked???) stuff. But then, that wasn't the question. I said I turned off the hard discs that make noise when I do non-DI'd stuff, while the iMac itself is virtually noiseless.

By the way... I love the Pod. I started out with a Flextone when the thing was barely invented, but most of the time I play through my trusty Pod 2.0 with a floorboard.
 
There is a very very low hum. It's probably the fans and/or hard drive, but honestly unless you are listening for it and in a very quiet room you won't notice.
 
My brand new iMac (24" 2.8Ghz) is wonderfully quiet. The only slight noise I get is from the external drive. To help quiet an external drive, I place them on a rubber pad. I used to run a PC and an old dual G4 and the noise was awful. I can now work in peace and quiet :)
