I'm not sure about the dates but it was july or august '05 that I had it up & runnning. I first heard of os x going intel on slashdot. Building my own mac had been a dream ever since I realised my first powermac was neither going to do what I needed it to, nor be upgradeable. I next found the leaked 10.4.1 dev.kit DVD on a torrent site, and realising as the information became available on IRC (#osx86 on r-type.ca, the same channel that lives on to this day as #osx86 on moofspeak.net) that none of my existing hardware would cut it, I ordered an intel motherboard, celeron d (cheapest sse3 cpu I could find, the sse2 patch wasn't ready at this stage) and a harddrive online, and by the time it arrived I had the DVD downloaded, patched and burned according to the "state of the art" at the time, essentially just replacing oah750 with a patched version.
I remember well showing it to a mac user friend, who started looking around for the mac I had my monitor hooked up to, thinking it was hidden behind the curtain or something. It took a little convincing for him to accept that it was actually running on that homemade PC, and his only comment in the end was a begrudging "10.4.1 isn't the newest version anymore" (of course 10.4.2 never made it into hackintoshes due to paranoia about Apple watermarking the releases).
Install and setup from there was as if they had been made in a factory for each other, and the machine worked wonderfully,only niggle being the lack of sound input. I ran it (along with others I aquired along the way) up until about 10.5.1 when I decided it was getting old & replaced it. I miss those days, all bar the paranoia (Apple really was out to get us back then) but we are undeniably better off today with all the incredible leaps that have been made in technique..
Those early days of 10.4.1 -> 10.4.3 were a lot of fun.. underground, small, simple. There were no vast amounts of alternatives.. if you wanted a solution you had to invent it yourself, or do without. The hardest install ever was the first non-developer release, 10.4.4, which needed 2 partitions and a whole load of messing around as well as the first patched kernel (which is where the famous maxxuss first came into the legend) just to get it set up. This was the do-or-die point for osx86, and for quite some time it looked as though it might die. Many left the scene saying that now there were intel macs, there was no need for osx86 any more. That same 10.4.4 kernel was the basis of everything up to the first 10.4.8 releases.. stability somewhat suffering from the increasing "patchwork" nature of the releases, until finally Apple honoured their opensource commitment & released the source code to the xnu kernel around 10.4.8, and I got to watch semthex work on what became nebuchadnezar 8.8.1 (iirc) one of the first from-source kernels to come out (the other one of note being the slightly earlier, but intel/sse3 only kernel from mifki) It is strange and ironic that the arrival of open source actually split the community and caused more disharmony & wars than any other event, all happily behind us now.
Worth a mention is the "Ultra Crapintosh" which for a while held the record for the lowest recorded xbench.. it was a celeron 1.7 with 256mb ram , a 10gb IDE harddrive & a non-supported nvidia gfx card running in VESA mode. I think its overall xbench score was 17, and believe it or not, after I bricked my intel board with a bad bios flash, I ran it for a while as my main machine, doing all my daily work from it.
Happy days
