We've shown you how to build your own "Hackintosh", a computer running Mac's OS X system with PC parts. Now The Wired How-To Wiki goes even cheaper, detailing a process for installing the Apple OS on the ultra-portable (and pretty cheap) Eee PC. The method explained requires finding a suitably tweaked OS X image, an external DVD drive, and the patience to run through all the system configuration and terminal tweaks. Once you're up and running, however, the author says it runs decently swift, even with just the stock 1GB of RAM. Hit the link for a complete walkthrough.
