I created a wiring harness from the ATX extension cable using various connectors from my spare parts bin. There are multiple power supply connections needed inside the case. I used this cable - similar cables are available from other vendors. In addition, I used a separate breakout board for the power, ground, and VEDID (+5V from iMac power supply), and Hot Plug Detect circuitry.ДЄs mentioned in Kiwi's procedure, it is easiest to use an ATX extension cable so that you don't need to cut the original cable coming from the Apple power supply. HDMI ConversionДЄdafruit has an HDMI breakout board which makes soldering the tiny LVDS video wires from the LCD much easier compared to the surface-mount connector in Kiwi's procedure. My project also has a simpler SMB implementation, and uses what I believe is an easier method of converting the LVDS wires to an HDMI connector.

However, certain steps are changed to accommodate the Raspberry Pi vs. The major parts of the conversion follow Kiwi's detailed procedure. I decided to use a similar procedure to convert my iMac into a Raspberry Pi: the 'PiMac'. I came across this project by Kiwi, which converted an iMac G5 into a 'Hackintosh' by reusing the display and power supply and replacing the system board with an X86 motherboard. I had previously converted an old iMac G4 to a 1680x1050 DVI display using a procedure by Dremel Junkie, and was now looking to re-purpose my old iMac G5. I had an old iMac G5 in storage which, while obsolete, still had a nice 1680x1050 LCD display that I didn't want to throw away. The 'PiMac' - converting a 2005 iMac G5 into a Raspberry Pi desktop.
