FYI...
Fry's has a sale on the MSI 945 Saturn Barebone System for $89 - $20 rebate = total cost $69. Looking at the specs on this system, it looks like it would be pretty compatible with running OSx86.
Here is a link to the specs:

It uses a Realtek ALC888 for audio and a Realtek 8111B LAN port. Throw in a CPU, memory, optical and hard drive and you can have a Mac clone for cheap. It has integrated graphics but if you want, throw in an inexpensive nVidia card.
I don't have any personal experience with this particular system, but I have installed OSx86 on other systems with the same chipsets with success. For the price, it looks pretty good...
