UNDATED (CNN) -- Apple fans will wait in line for hours to buy the newest iPhone, but you should see what some of them are willing to pay for a 37-year-old computer!

Monday, an auction house in New York opened bidding on one of the few remaining original Apple 1 computers. Christie's Auction House expects the computer to sell for between $300,000 and $500,000.

There isn't much to it. The circuit board, built in 1976, didn't even have a casing. Only about 200 of these computers were ever built.

It was the first product designed by Apple co-founder Steve Wozniak, who built it in Steve Jobs' parents' garage.
