Nic Lindh writes an entertaining and informative story about building his Hackintosh:

The complexity is also high. Remember, you’re dealing with something completely unsupported that is by its very nature complicated. You’re picking parts, tweaking BIOS settings, installing strange system extensions, and groveling through more-or-less-illiterate testosterone-soaked forum discussions trying to pick up clues on how to fix something that’s not working. The learning curve is steep.

Every once in a while I think about building one of these myself, but I don’t have long weekends to go get lost in much anymore. I think I like reading about it more than I would like the never-quite-done fiddling, despite the on-paper cost savings for a high-power Mac.
