I should weigh in here as well. Recently built my first Hackintosh over the past few weeks.
Components used:
Gigabyte GA-EP45-UD3P Motherboard
Intel Quad-Core Q9550 Processor
4GB Corsair DDR-800 Memory (4 more gigs to be added shortly)
256MB eVGA 8600GT
2 750 GB Sata Drives for OS
1 100 Gig SATA drive for Windows Separate Boot
Using the USB-Drive to boot the 122Boot loader, didn't use the chameleon loader.
OCZ 500Watt PS
Antec Three Hundred Case
Vanilla Leopard Install
Everything works beautifully! The *ONLY* problem I have encountered is with iSale right now. I have contacted Equinox support for options. I have heard of another guy who had problems with iSale, and it was due to some of the shared web library extensions from a specific version of Safari on his system. So, this MAY not necessarily be due to my system being a Hackintosh. More to come on that later. Beyond that, everything works GREAT!! I couldn't be happier.
EDIT / UPDATE : iSale support provided me with the following recommendation which fixed my problem. As an FYI, I had installed this program on my fresh Leopard install, but after performing the following actions everything works!
Please try deleting the following files:
"Macintosh HD/Users/YOURUSERNAME/Library/Preferences/com.equinux.iSale5.plist"
"Macintosh HD/Users/YOURUSERNAME/Library/Application Support/iSale5"
"Macintosh HD/Users/YOURUSERNAME/Library/Caches/com.equinux.iSale5"
Please note that doing so will delete your auctions and preferences as well, so make a
copy of them if you need to access your old data
