ifixit: 27" iMac Teardown

The Mac mini unibody teardown impressed me so much I thought I would post this also.

What surprises me most is how Apple manages to pack full size desktop components (including video card up to a HD4850 512 MB for the high end model) into such a tiny form factor.

How much internal volume are we looking at here? Maybe 3 liters?? (In contrast Sugo SG05 is ~10 liters and a 1U mini itx case capable of similar size Discrete Video card is ~5 liters)

And check out the Power supply depicted in step 12. That is a 330 watt fanless unit with 25.8 amps on the 12V rail.

Comments? Does anyone know about noise levels?

Recently, I got a chance to see one of these 27" iMacs in person.

The model I looked at was the 3.06 Ghz Wolfdale/HD4670 256MB entry level model.

Noise (@ idle): Difficult to determine at Best Buy due to ambient noise.

Heat (@ idle): The back of the chassis definitely felt very warm to the touch in several locations. The hottest location being the top of the monitor in the back where the elongated exhaust vent is located.

Overall this product looked extremely well built in person. Hopefully at some point I will be able to get a demo (with some type of load test) of the Core i7/HD4850 model in a fairly quiet environment. Maybe a nearby Apple store could do this for me?
 
If you go to a nearby apple store, and start streaming a bunch of 1080p videos you should get a pretty good load test for CPU/GPU. If you just want to stress CPU then go to the store, open terminal, and type 'yes'. Hit CMD+N a few times to get multiple sessions and do the same in each window. Quick and dirty stress test.

They are incredibly well built, and a little intimidating in person. I set my 12" PowerBook next to one... freaking dwarfed it completely.
 
yeah they should have just done a proper S-IPS 30" wide-gamut 2560x1600. 27" is not industry standard.

I have an i5 model with the HD4850. The upper rear section does get VERY HOT to the touch, but that is normal. The aluminum rear acts like a heat exchanger/heatsink of sorts. It's normally just warm, but when encoding video using 4 cores, it gets too hot to touch for more than a few seconds. Even in a quiet room, I can't hear any sound until I start encoding video, then I can hear the fans. It's still not loud, but somewhat noticeable. It's definitely quieter than most PC's in my experience.

Agreed.

I would have liked the 30" also, but this IPS 2560 x1440 still does strike me as a very high standard. (I figure anyone else would have used a 1080p TN)

This makes me wonder what Apple has planned for the iMac when OLEDs and Stacked OLEDs come out?

Today's press release on the new iMac and other accessories (Magic Track pad, etc).

http://www.apple.com/pr/library/2010/07/27imac.html

Apple Updates iMac Line
Introduces New Multi-Touch Magic Trackpad

CUPERTINO, California—July 27, 2010—Apple® today updated its all-in-one iMac® line, widely praised as the world's best desktop computers, with the latest Intel Core i3, Core i5 and Core i7 processors and powerful new graphics. Starting at $1,199, the new iMac line is the fastest ever with dual-core processor speeds up to 3.6 GHz, quad-core speeds up to 2.93 GHz and discrete graphics including the powerful ATI Radeon HD 5750. The new Magic Trackpad, with a smooth glass and aluminum design, gives iMac users the same intuitive Multi-Touch™ gestures that Mac® notebook customers have come to love and is available separately for $69.

“We took the world’s best all-in-one and made it even better,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “With the latest processors, high-performance graphics and signature aluminum and glass design, customers are going to love the latest iMac.”

Dual-core Intel Core i3 and Core i5, and quad-core Core i5 and Core i7 processors set a new benchmark for iMac performance. The processors feature an integrated memory controller to access the system memory directly, allowing the new iMac to take full advantage of its faster 1333 MHz memory. New discrete ATI Radeon HD processors deliver incredibly smooth, crisp graphics for the most demanding 3D games, creative software and technical applications. iMac displays feature IPS technology to deliver a brilliant image across a wide 178 degree viewing angle. The SD card slot on the iMac now supports the SDXC format to handle the latest high-capacity storage cards. Customers of the 27-inch iMac have the option to order a 256GB solid state drive (SSD) as a primary or secondary drive. The iMac SSD supports up to 215 MB/s data transfer rates for faster startup and application launch times.

Every iMac comes with Apple’s innovative Magic Mouse and customers can also order the new Magic Trackpad as an option. The Magic Trackpad brings the intuitive Multi-Touch gestures of Mac notebook trackpads to the desktop. With its glass surface, the wireless Magic Trackpad enables users to scroll smoothly up and down a page with inertial scrolling, pinch to zoom in and out, rotate an image with their fingertips and swipe three fingers to flip through a collection of web pages or photos. The Magic Trackpad can be configured to support single button or two button commands and supports tap-to-click as well as a physical click.

Continuing Apple’s commitment to the environment, Apple’s desktop lineup is a leader in green design. The iMac meets stringent Energy Star 5.0 requirements and achieves EPEAT Gold status.* iMac features LED-backlit displays that are mercury-free and made with arsenic-free glass. iMac uses PVC-free components and cables, contains no brominated flame retardants, uses highly recyclable materials and features material-efficient system and packaging designs. A new Apple Battery Charger provides a convenient and environmentally friendly way to always have a fresh set of batteries for your Magic Trackpad, Magic Mouse and Wireless Keyboard. The Apple Battery Charger is available for $29 and comes with six long shelf life rechargeable batteries.

Every Mac also comes with Mac OS® X Snow Leopard®, the world’s most advanced operating system, and iLife®, Apple’s innovative suite of applications for managing photos, making movies and creating and learning to play music. Snow Leopard builds on a decade of OS X innovation and success with hundreds of refinements, core technologies and out of the box support for Microsoft Exchange. iLife features iPhoto®, with breakthrough ways to organize and manage your photos by who appears in them and where they were taken; iMovie® with powerful easy-to-use features such as Precision Editor, video stabilization and advanced drag and drop; and GarageBand® which offers a whole new way to help you learn to play piano and guitar.

Apple designs Macs, the best personal computers in the world, along with OS X, iLife, iWork, and professional software. Apple leads the digital music revolution with its iPods and iTunes online store. Apple is reinventing the mobile phone with its revolutionary iPhone and App Store, and has recently introduced its magical iPad which is defining the future of mobile media and computing devices.

In addition to updating HD4670 (256 MB VRAM) to HD5670 (512 MB VRAM) on the 27" iMac Apple has also added the option of a 256GB SSD drive (which AFAIK is a first for them).

Which part is the first, the SSD (First appeared in the MacBook Air, then became an option in the MBP. This is the first desktop with an SSD though), or the second drive in the iMac?

I appreciate you pointing that out to me.
