Cracking Open the 27" Apple iMac (2011)

27" Apple iMac teardown (Model: A1312)

In 2011, Apple updated the iMac line with Intel's second-generation Core CPU family and AMD's new Radeon HD 6000-series graphics processors. Apple also replaced the old Mini DisplayPort input with a Thunderbolt port.

In March, I took a look inside the HP Compaq 6000 Pro All-in-one Business PC and couldn't wait to see how the new iMac compared. Follow along as I crack open the 27" Apple iMac (2011).

Can anyone tell me what the wire colours refer too in the Broadcom BCM92046MD Bluetooth module? I need the USB power D+ and D- from the old module to go into the new bluetooth 4.0/WiFi card

You can get them for cheaper at a pet store that sells aquarium supplies too.

I use two 2" suction cup to lift the front cover screen. It also makes for an easy way to handle the cover once it's off. You can buy these suction cups at bathroom supply section of most hardware stores for about $3.00.

I am maintaining iMac PCs here in the Middle East and I had discovered some colored and back lines in the display. We have 25 IMac PCs and the number of faulty LCD is increasing. Is there any way how to solve this problem? Help please.

I hear on Mac Rumours that Apple have changed the pins on the HD so that you have to use an Apple branded unit - is that so on your stripped HD?

Is it possible to get an integraded slideshow? It's quite annoying to let the entire website load when clicking next. Keep up the good work

IR 9310: -30v Power MOSFET. LFE9249-R: Lan filter chip H82/2117RV: Subprocessor- Sold as "Single chip microcomputer" I don't know what they're using it for, but it's an amazing little self contained PC on a chip. tps3117: Audio amp lvc08a: quad 2-input and gates. SMSC 1428: Multiple Temp monitor with thermal shutdown PS8301: Looks like a DisplayPort chip, but Parade technologies doesn't list it. All the 83xx chips seem to be related to DisplayPort switch applications. The manufacturing date off 0711 is either in the future (Jul of 11) or Nov of 07. If they're using a chip that old, they may have bought the entire run of the chip meaning it's a specialized chip just for Apple.

in this unit are better designed than the delta fans in my ASUS notebook, or else they are going to have a very high failure rate. The ones in my notebook last about 14-16 months, then start vibrating really bad. I only say this because it has almost the same shape, even if I can't read the part number on this one.

bill i love the big mac tear down but so hard to match up the pic and the description .. i am wondering if you can match up on screen so one can read the words right on top of the picture or to one side .. maybe a carousel with description showing as you look at picture then fading away as one goes to next picture ... i tried to tweet this to you but i find twitter difficult to wrap my mind around too ... maybe i a Ludite

So if you had an equally strong magnet, you could hold it up to the screen with the reverse polarity towards it and lift it away like magic?

why hasn't Apple decided to go USB3 yet? :)

That's a lot to look through Bill. Still good but takes a very long time. ;) Col

image 10... Where's the Mini Display Port? I see the audio in/out, the 4 USB2 ports, the FireWire, the 2 Thunderbolt, and the GigE port, but where's the Mini Display Port?

Don't see the duct tape or glue. Did they finally stop using it or was it just cut out of the pics?

Had that straight out of the box last week. Two Blue lines and a thick red one down the left side - Apple exchanged it.

Zorched-- I used to work in the chip design software arena, and 0711 usually means that it was made in the 7th _week_ of 2011, or the week of Valentine's day... which is possible, given that this is May. :)

Not to be used near MRI's or any other Magnetic Sources. I can just see the Insurance Claim Form now Operator X was hit in the head by the Screen Cover flying off in it's attempt to destroy the Magnetic Imaging Equipment in the room. :^0 Col

If you look at the features of Thunderbolt, you have to ask, why would I want USB3 if I can get Thunderbolt devices with the same capabilities.

Yeah. This one was probably the upper limit of what I would do in a cracking open gallery. If you use the "View all thumbnails" link below the image, you can see all the thumbnails and then skip around to the ones that look the most interesting.

As on the latest MacBook Pros, the Thunderbolt ports also act as a Mini DisplayPort--same shape. I have been using a Mini DisplayPort to HDMI adapter on my MacBook Pro's Thunderbolt port for a few weeks now. It works, but I have an intermittent problem with the adapter getting hot (very warm to the touch) and the display cutting in and out. I've read forum post on Apple's support site about similar problems, but no about the adapter getting hot. I think there are still a few bugs to work out with the Thunderbolt/Mini DisplayPort jacks.

Are you referring to a specific image title or description in this gallery?

Unlike some of Apple's other devices (iPhone, iPod, iPad, and MacBook Air), the 27" iMac doesn't use any tamper-resistant screws, just standard Torx and Phillips.

that have mixed Mac and PC environments.. Most of our PC laptops have FireWire ports on them, so using FireWire/USB drives is commonplace for us... we don't want to support an additional interface type, or have to buy a 'different' drive... I routinely use a G-Drive Mini (500GB, 7200RPM, FW800/USB2) between my MacBook Pro and my HP EliteBook 8540w... I haven't heard of any PC manufacturers that are shipping Thunderbolt--in fact, it's apparently Apple-only until next year...

I know about the Thunderbolt/MiniDP ports... we're getting MacBook Pros in at work that have them, and we're having the same problems--heating and display issues... My question was that the caption says "two Thunderbolt, one Mini Display Port"....
