In case you missed it, Psystar's new downloadable software lets you install OS X on any PC with a Core 2 Duo, Quad, i7 or Xeon Nehalem processor. CrunchGear tried it on an HP TouchSmart, and even the touchscreen worked.
Turns out the OS X install screen takes ages to come (they thought it had crashed), but with some patience they had themselves a hackintosh.
Psystar says the $US50 download allows for the permanent installation of multiple operating systems on a single system, and that it works with Windows 7. A trial version is available (with a two-hour time limit), and comes with all the expected warnings of them not being responsible for you losing your data should thing go awry.
