SATA drives can report temperatures via S.M.A.R.T. I have a Vertex 3 that i've briefly used under linux and it can report temperatures fine on its own without the need for any external temperature sensors. You'd be hard pressed to find a drive that cant.

I see. That sounds good, but..

My understanding is that it's done with internal temperature sensors in the drive itself, combined with Apple Firmware on the drive and a proprietary cable. Each brand of hard drive used has a different proprietary cable and Apple Firmware.

Does that mean the Vertex 3, even though it has the capability, would not be able to report its temp to the system since it's not running Apple firmware?

I don't know if the proprietary cable and firmware applies to SSDs.
 
Some people remove the optical drive and use it as a hard drive bay.

Before Thunderbolt this was almost necessary for some people. Now, you can keep that optical bay in there. Though, this is a sign of how the optical media is slowly becoming redundant. Can't wait to step around all optical media, myself.
 
I think the only feature on my iMac that gets used less than the optical drive is the iSight camera. I don't think it's necessarily a good idea to do away with the optical bay on a desktop computer, but I certainly understand why many users do this. The optical drive is one of the only things on my system that's ever given me any grief (randomly gets super loud and clunky once in a while, and occasionally has serious trouble reading disks that work fine on all my other systems).

The proprietary part of this HD-temp system is actually caused by the drive manufacturers. Each different manufacturer makes their own temp sensor, and thus you can really only replace like-for-like (i.e. Seagate for Seagate) in the iMacs if you want proper fan functionality. The cables are all the same (normal SATA), it's just that the EFI is configured to look for a certain signature of signal. I don't know if it's possible to change this.
 
The optical drive must die. I seriously hope that Apple gives the option to swap the ODD for a battery/HDD/SSD/RAID/less weight.

I've used twice since I had my MBP. One was an Handbrake rip I could have done at home with my USB ODD (got that since the eeePC days), the other was installing some Windows 98 old as hell software via Parallels. I even happened to have the ISOs, just forgot them on my pendrive at home and had to use a spare copy.

I'd swap my ODD for everything, ranging from a battery to a 3G modem. Just take it out.

Knowing Apple though, they'd probably move existing components into the newly freed up space, and make the laptop slimmer. It seems to be the direction they've been heading in lately.
 
I just bought the 21" iMac but didn't spring for the SSD from Apple. I just picked up the intel Sata 3 40 gig from Amazon. I've looked at the pictures from iFixit and I'm wondering if I'll need some sort of bracket or hardware to attach the ssd?

Make a video when you do it. I'm interested.
 
I'll think about it. I'm not sure MacRumors could handle that much swearing. :)

Meh. Thinness and extreme portability should be an "Air" key feature, "Pro" notebooks should rely on horsepower and expandibility. I don't honestly think that they will make compromises on connectivity (that includes the ODD) in order to make the Pro line more similar than the Air line. They would just cannibalize each other, and they have to keep an all-in-one notebook (ethernet, FireWire, bigger storage space, ODD) for people that do something with $1000+ computers other than running Office and browsing Facebook. Non-user replaceable RAM/HDD? Low voltage CPUs? No ODD? How can you call that a "Pro" computer?

Yeah if there's not some kind of firmware/patch to change it normally/correctly, as mentioned above SMC or any other fan controller can allow you to do it manually. I use iStat to ramp up my fans when my ssd in my MBP expansion slot gets a little warmer, but since my comp isn't normally looking for a drive there it doesn't make the fans go crazy unless I tell it to, so I haven't tried spinning them down any.
