Although beautiful, strange and / or "different" (it goes from the point of view of each one), the first generation of the iMac is considered, like a lot of other machines, obsolete on the part of Apple because the hardware of some is very limited for running the current versions of Mac OS X. However, probably thinking about surviving one of its models, a user had an idea that in the current times of fighting between Psystar and Apple it is not at all correct: turn it into a Hackintosh.
The process adopted by him may not be very simple for some, but theoretically possible: the machine has a good internal space that makes this possible, not to mention the connections (almost) defined for peripherals and the location of the DVD drive. The only problem deciding which hardware to use for the images, note that he opted for a 1.87GHz Intel Core 2 Duo CPU, with 1GB of SDRAM and integrated GPU.
In this case, the operating system installed was Mac OS X 10.4 Tiger. I imagine it is possible to be bolder than that: John Brownlee, from Cult of Mac, said he will try to transform an iMac G3 Indigo he has on his desk into a Hackintosh, then we will see if it is possible to better explore its internal space for such madness or not.
You can check out more photos of the transformation process by going to the website of the user responsible for this iMac G3.
