The final selling price includes a 25% "buyer's premium" fee that RR Auctions, the auction house that listed the fully functional Apple-1, adds to the hammer price. What made this particular one even more rare, however, is that it came housed in a wooden Byte Shop case. According to RR Auctions, only nine Apple-1 computers in Byte Shop's wooden case are known to exist. Enter the wooden case, which proved pivotal in the Apple-1 becoming one of the first PCs to come fully assembled. It was also recently restored to fully working order, in case the winning bidder cares to fire it up.
