OSx86 OpenMac clones was apparently pretty popular -- we saw a note from the company saying it was trying hard to cope with the rush of traffic, but it looks like things got overwhelming, and the site is now unavailable. People are speculating that Apple already shut things down, but that's pretty unlikely: nothing on the Psystar site infringed any of Apple's IP (as far as we can recall) and the company hadn't actually sold anything yet, which means there isn't much of anything for Apple to go to court over. On top of that, we doubt that Psystar wasn't expecting to attract Apple's attention, so we don't think a cease and desist letter would scare the company into shutting things completely down. Of course, we're still willing to bet that Apple's legal team is licking their chops in anticipation of something actionable happening, but we'd say the most interesting thing about this so far is the incredible amount of attention a low-cost expandable minitower running OS X has gotten -- maybe someone at Apple apart from the lawyers should be taking notes as well.
Update: They're back! They've changed the name to "Open Computer," which should totally throw off Apple's lawyers. Or... probably won't.
