If you want to go the "Hackintosh" route, the best thing I've seen for no fuss, no muss is efi-x. It's a USB dongle that attaches to the internal USB header on supported motherboards and will allow you to install a full, retail copy of OS X on supported hardware, take software and system updates, etc. It's a bit pricey at around 199 dollars, but it's worth it if you're looking for the OS X experience without having to a) shell out for Apple hardware at Apple prices or b) looking to build your own OS X rig without having to resort to hacked kernels, modified kernel extensions, etc., and the worry of possibly having your system go boom on the next system update.
Here's a nice little quirk though. The US distributor of EFI-X is charging 199 dollars for the product. However, the highly reputable Swiss dealer is charging €128 for it. At today's exchange rate, that's ~$162. So if you want to save yourself a little scratch, order through the Swiss dealer.
If you're willing to build your system using the hardware on the compatibility list, you're going to have one rock solid system that supports OS X out of the box.

I'm close to building a few systems using this. One for myself and another for a friend that does video editing. From reading the forums off of the main site it appears rather straighforward and most people's problems are caused by building with stuff not on the HCL.
Just another option for ya.
