I bought %70 of the parts needed to build one myself. But the eprom chips have the preloaded software from Apple. And not to mention the flash hard drive. What I did do was order from A web site called Dealextream about %50 of the unit. We in Toronto Ontario Canada have a mall called Pacific mall. In it has about 200 small china like stores with the rest of the imports for the Ipad. You are almost assured that most stores only carry Ipad 1 parts in stock. Cost to date is about $300
Good luck
