Update: According to EFiX creators, Art Studios Entertainment, this product was launched by distributor EFiX USA without authorization and thus plans to sell “Millennium” machines capable of running OS X have been shut down just hours after they were announced.

Back in September, EFiX finally began shipping their so-called USB dongle that lets many generic PCs run Mac OS X. Now, even with Psystar struggling against Apple in courts for outright selling Mac clones, it looks like the company is taking things one step further and plans to offer customers a solution for creating their own OS X-running computers.

The EFiX Millennium 4 will reportedly be targeted at the performance crowd, sporting a Core 2 Quad processor overclocked to at least 3.8GHz, 4GB of memory, a 10,000RPM hard drive and a GeForce 8800 GTS graphics card in an Antec P180 case. Priced at $1,899 (not including the additional cost of a $199 EFiX dongle), the system will reportedly offer up to 90 percent the performance of a top-end Mac Pro for less than half the price.

Unlike Psystar, the company hopes to avoid a legal response from Apple by leaving the installation of OS X up to the end user, which I’m not sure how good of a tactic it will be considering it’s illegal to sell a product expressly designed to allow customers to infringe copyrights – then again, it’s precisely the validity and scope of Apple’s EULA which has recently been brought into question. Stakes are high in the Apple vs. Psystar case and the outcome will certainly have an effect on EFiX latest efforts as well.
