Yes its possible, but illegal under Apples software EULA. The site
you linked to has a nice disclaimer:
"The OSx86 Project and its subsidiaries (referred to as "OSx86") provides an unmediated medium for the > communication of information related to Mac OS X for Intel based machines. OSx86 does not in anyway > condone the piracy of copyrighted material that may or may not be related to the information found on this > website and/or related services"
In other words it's not illegal to discuss or even demonstrate to
someone the feasibility of installing OS X on a plain vanilla PC
but it is illegal to actually obtain OS X and do it.
Many people knowledgeably breaking the law and pointing out to
others how to do so doesn't seem right (to me)
