I've been on a hack since 10.4. Depending on the hardware, it can be easy or a nightmare. If your someone like me, who will not be satisfied until everything works 100% then be prepared for a challenge. Since most of us have *nix skills and enjoy tech, you'll probably find it fun like I do.
Currently some of the most compatible motherboards are by Gigabyte. I use a EP45-UD3P. Here is a thread I maintained for 10.5. Can't be used for SL, but the level of effort is similar. I do still recommend the hardware though, it has been rock solid and very compatible. I run it in 64bit mode.http://www.insanelymac.com/forum/index. ... pic=163899
