John Fraser, a 21-year-old engineer from Chanhassen, Minnesota, is finalizing the design for his flat "pizzabox" Mac and hopes to go into production in three to four months. If successful, Fraser will be the first third party to make a Mac since Apple shut down its three-year experiment in clone licensing in 1997.

Unlike the world of Windows PCs, which has many hardware makers, Apple is the only company making Macs. Apple doesn't license its operating system to outside hardware manufacturers.

Fraser hopes to sidestep the licensing issues by using older, off-the-shelf parts made by Apple and sold to computer repair outfits as spare parts. He will use Apple-made motherboards preloaded with Macintosh ROMs -- the vital piece of hardware-***-software that makes a Mac a Mac. Customers will supply their own Mac operating system....
I'm sure this guy will be swamped with law suits in no time.
