Very, very informative thread with lots of very useful info and a very nice OP guide CoBrA2168!
I am considering building a new ML system with new hardware since I've had good success doing it on my Asus G73JH laptop. Have to admit that in order to get audio to work and the keyboard backlighting I've had some help from a few very friendly community guys (also on osx86).
My main system upstairs will probably not handle an attempt to hackintosh it very well since it is at least 4 years old.
Any things I should be aware of when actually buying components? Not sure if rev 1.1 or 1.0 makes a difference on the mainboard. Not sure which exact graphics card I will get but I'm gathering that any similar GTX 660 2gb should be ok and it wouldn't matter that much which exact brand it is. Hopefully I'm right about that. I am also assuming that the actual brand and type of memory (planning to put in 1600-16gb) doesn't really matter as long as it is supported by the mainboard.
In any case, how is your system performing and doing on Win7 ? (or perhaps Win8) and on ML? I mean more in a real life scenario instead of raw benchmarking scores. Since I'm mainly a Windows guy (actually using all Windows systems professionaly as I'm a support/windows engineer). So I'm aiming to get a top notch Win7 system and hopefully a near perfect ML 10.8.2 system.
Thanks for the kind words! I treat this thread as my contribution to this awesome community which helped me get started in the first place. I've also made an application that helps sync iTunes on a dual-boot system that I wish someone would help me test!
To answer your questions:
1. Yes the revision on the motherboard DOES matter. The rev 1.0 board has an issue where only one of the rear audio jacks will work in Linux/OSX (black only). Also the front headphone jacks won't work in Linux/OSX either. They work fine, however, on a Windows OS. Rev 1.1 corrected this. On the other hand, I think rev 1.1 uses a different ethernet controller for one of the 2 ethernet ports. I believe that this new one doesn't have a working kext for OSX at this point. Don't quote me on this - I'm not 100% sure on that.
2. Video card and memory brand I don't think should matter. I've never seen anything on here that recommends or requires a particular brand of memory. As long as it fits into the motherboard, you should be good. And I think GTX 660, 670, and 680 all pretty much work natively on ML. Someone correct me if I'm wrong here...
3. I'll be honest with ya - I use Windows more too. This computer I built is probably running Win7 85% of the time. The reason I built this computer (other than for the challenge) was for programming and some gaming. Right now I'm working on a project in Windows which is why I'm on that more often than not. What's really nice is, getting into OSX is just a quick reboot away (and when I say quick, I'm talking like 9 seconds tops). Also, this computer is on probably 8-10 hours a day, and it is very stable. I got my first BSOD in Windows the other day, which could be attributed to a couple things (just recently installed MS Visio, SSD glitch, etc.). Overall, I can't complain.
