    • Apple's "affordable powerhouse" offers a range of hardware configurations (but no gold color option, so you can't configure for bling). Our unit's internals include:

    • 1.4 GHz Dual-Core Intel Core i5 (Turbo Boost up to 2.7 GHz) with 3 MB L3 cache

    • 4 GB of 1600 MHz LPDDR3 memory

    • 500 GB Hard Drive

    • Intel HD Graphics 5000

    • 802.11ac Wi-Fi + Bluetooth 4.0

    • OS X Yosemite

  2. Mac mini Late 2014 Teardown: 手順 2、 2の画像 1 Mac mini Late 2014 Teardown: 手順 2、 2の画像 2
    • The backside of the mini remains almost identical to the previous iteration. The only change is the omission of a FireWire port in favor of an extra Thunderbolt 2 port.

    • The Mac mini Late 2014 retains the model number identifier of A1347, but is distinguished by the EMC number 2840.

    • Gone are the handy thumb indents and indicators. This mini doesn't appear to have twist-off bottom cover!

    • We've got a bad feeling about this.

    • A flick of our bottle opener plastic opening tool pops this (lower) cap off.

    • Well that was nice! But now we're greeted with something new: a solid door where there was once handy access to the RAM and fan.

    • We're starting to feel like the locks on our apartment changed and we weren't given the new keys...

  4. Mac mini Late 2014 Teardown: 手順 4、 2の画像 1 Mac mini Late 2014 Teardown: 手順 4、 2の画像 2
    • Time to break down the door and see what's changed inside. The plastic bottom cover snaps onto three screws—three TR6 Torx Security screws. Really? Rude.

    • This is the smallest Torx Security screw we've ever seen—our kits go down to T7 Security, so we asked our tool design team to get improvising.

    • Improvisation complete! Our packrat engineers produced a lone prototype T6 Torx Security screwdriver, a tool we originally abandoned because nobody had seen such a screw used in real life

    • Thanks, Apple.

    • We'll get this ridiculous driver in the store shortly.

    • After a bit of work—more than we were expecting—we're able to flip the Wi-Fi antenna/shield plate out of the way.

    • Unfortunately, we're not home free yet. One end of the Wi-Fi antenna cable is clamped firmly to the plate, while the other end is screwed down onto the logic board.

    • Upon removal, the fan seems identical to the one from the previous model—but let's not be too quick to judge a fan by its cover.

    • Advanced Hydraulic Bearing

    • Hmm. Interesting. What exactly is Advanced Hydraulic Bearing? Let's find out. According to Asia Vital Components:

    • AHB "consists of a polished steel shaft, a sintered bearing and fluid lubricant." In this system there "is no contact between shaft and bearing" and thus "the bearing load is carried solely by a film of fluid lubricant."

    • AHB is best for fans that operate at a lower speed. It's better at absorbing shock and dampening vibration than traditional ball bearings, making for a quieter fan.

    • The AirPort card is dispatched after removing one screw and disconnecting two more antennas from their sockets.

    • Gone is the funky cable-connected AirPort card of yesteryear, this AirPort card is now full-fledged PCIe, supporting Wi-Fi ac.

    • Let's take a look at the ICs found on the AirPort card:

    • Broadcom BCM4360KML1G 5G WiFi 3-Stream 802.11ac Gigabit Transceiver

    • Skyworks SE5516 Dual-Band 802.11a/b/g/n/ac WLAN Front-End Module

    • RF Micro RFFM4293 2.5 GHz FEMS and RFFM4591 5 GHz FEMS

    • Broadcom BCM20702 Single-Chip Bluetooth 4.0 HCI Solution with Bluetooth Low Energy Support

    • Using our handy hand-powered Mac mini logic board removal tool, we handily remove our Mac mini's handsome logic board.

    • While past Mac minis have featured two SATA ports, allowing users to upgrade their base model with an extra hard drive, this year we only get one.

    • However, this empty socket over here may well be a spot for a PCIe cable, enabling the installation of a blade SSD.

    • More on this once we get our hands on a Fusion-equipped Mac mini.

    • True to our word, we cracked open a Fusion drive equipped Mac mini, and it looks like our suspicions were accurate.

    • The empty connector is now filled—by a PCIe cable, glued to the top of the hard drive tray.

    • The SSD matches the one we found in the MacBook Air 13" Mid 2013 with the same chips:

    • Samsung S4LN053X01-8030 (ARM) flash controller

    • 8 x Samsung K9LDGY8SIC-XCK0 16 GB flash storage

    • Samsung K4P2G324ED 512 MB RAM

  9. Mac mini Late 2014 Teardown: 手順 10、 1の画像 1
    • Let's have a look at the ICs on the logic board:

    • Samsung K4E8E304EE-EGCE 8 Gb LPDDR3 DRAM (8 Gb x 4 = 32 Gb = 4 GB)

    • Unfortunately, the RAM is soldered to the logic board. This means that if you want to upgrade the RAM, you can only do so at time of purchase.

    • Cirrus Logic 4208-CRZ Audio Codec (a returning champion from a bevy of recent Apple products including the Mid 2013 MacBook Air and Mac Pro)

    • Broadcom BCM57766A1KMLG Ethernet PCIe Controller with SD3.0 Card Reader and ASF 2.0

    • Intel DSL5520 Thunderbolt 2 Controller

    • Delta Electronics LFE8904C-F Discrete LAN Filter

    • NXP 6142F and NXP PCA9501BS 8-bit I/O Expander

  10. Mac mini Late 2014 Teardown: 手順 11、 1の画像 1
    • The IC party continues:

    • Microchip Technology 1428-7 420BE5A BMY System Management Bus (SMBus) Temperature Sensor

    • Cypress Semiconductor CY7C63833 LTXC enCoRe II Low Speed USB Peripheral Controller

    • Texas Instruments TPS51916 DDR3 Memory Power Solution Synchronous Buck Controller

    • Texas Instruments 58873D Synchronous Buck NexFET Power Block MOSFET Pair

  11. Mac mini Late 2014 Teardown: 手順 12、 1の画像 1
    • The IC after-party:

    • Intel Core i5-4260U Processor with Intel HD Graphics 5000

    • Texas Instruments/Stellaris LM4FS1EH Microcontroller

    • Parade PS8401A HDMI Jitter Cleaning Repeater

    • Macronix MX25L6406E 64 Mb CMOS Serial Flash

    • Delta Electronics LFE8904C-F Discrete LAN Filter

    • Intersil 958 26AHRZ M419VL

    • We've got the power (supply) at the tips of our fingers. It's an easy extraction, even if it took a while to get here.

    • We get a slight rush before we realize it is the same as the 2012 model...which was the same as the 2011 edition.

    • In the immortal words of Gertrude Stein, "This is the lesson that history teaches: Repetition." (Put another way: Apple doesn't fall far from the tree.)

    • Before we go, let's pull out the hard drive tray and take a look at the platter drive our mini came loaded with.

    • Tucked under the tray: a 500 GB, 5400 RPM HGST hard drive, coming in at 2.5" wide and 7 mm thin.

    • And on the top of the tray, a promising mounting point for a blade-style PCIe SSD, presumably what we'll find in a Mac mini equipped with Fusion Drive.

    • To test just how promising, we dropped in the SSD from our recently torn down 27" Retina 5K iMac (and used its mounting screw). Looks like a nice fit!

    • Mac mini Late 2014 Repairability: 6 out of 10 (10 is easiest to repair).

    • There's no glue anywhere inside that needs to be removed while disassembling the mini.

    • With the proper tools, disassembly is straight-forward and simple.

    • T6 Torx Security screws are intended to lock you out of your mini, and make it hard to clean the fan or replace the hard drive.

    • The CPU is soldered to the logic board and not user-upgradeable.

    • The RAM is now also soldered to the logic board, and not user-upgradeable.

Is there an obvious size or accessibility issue that forced them into soldering the RAM down? I know Apple is all about sleek and slim, but was this necessary? 8GB isn't bad for a small workstation, but you can't ever have too much RAM. The option for the future would have been nice.

I think Apple was going for the simplest solution with the least amount of connections that could become loose. With the security screws, Apple obviously doesn't want anyone inside even though it appears to be easy to replace the hard drive, power supply, and fan. I see this as a commodity item where you replace instead of repair. I know that doesn't fit the mold of iFixit but at least they didn't glue it shut. If this model becomes the replacement for server farms, I would like to know how many Mac mini's are actually repaired when they fail and how many are simply replaced with new ones and fired back up (old ones either repaired or tossed).

Will iFixit be tearing down one of the higher spec mini models? I'm curious whether they have a secondary SATA connection and how replaceable are their SSDs.

I'm usually positive about new products but totally bummed about the Mac Mini line. I recently upgraded the ram on my Quad Core i7 Server to an undocumented 16GB, just by onscrewing the base and slipping 'em in. Felt great and made her run a lot more smoothly. Now I better take good care of her, because there'll be no more Quad Cores and no more user-upgradeable memory. And Apple couldn't give a shrimp. :-(

Are we sure that the higher end models will have soldered RAM as well?
