Where all old airplane go?

You can build an imitation flight deck out of plywood at much less expense and trouble than finding and purchasing the shell of a 737 flight deck. The part you are talking about is HUGE up close, and you would have to cut it into pieces to truck it home, and then reassemble it when you got it where you wanted it. Cranes, hydraulic jacks, and a crew of workers would be involved.

If you mean things like instrument panels, control consoles, control columns, rudder pedals, and seats, you are stopped before you start. These components are recycled in the industry, and if you could buy them, they would cost hundreds of thousands of dollars.

But aircraft designers build plywood mockups of aircraft flight decks that are quite realistic and function well for development and training purposes. So that is the recommendation: leave the old hull out in the desert, and build one from plywood and other available materials.

There are exceptions, and you might luck onto something. Try an internet search on "aircraft salvage." You will find lots of web sites and contact information for salvage operators that have the airplanes sitting around.

An airline I previously worked for had one of their pilots building cockpit mock-ups out of metal and some of the instruments from the actual aircraft. You could also put a computer screen where the instruments would go. Hooking it up to fly correctly would be tough, but could be done. You can also buy yokes and pedals and all that work with computers. This would be far more practical than buying real aircraft parts.

If you did what you say you want to do, you would end up with something very expensive that you would probably get tired of in a few hours. I heard of a company that used to build desks out of old flightdecks, and they were about 15 grand or so. I can't remember their name, but I'm sure a search would find them. Of course, hooking up everything to work correctly would be nearly impossible. Good luck.

Most old Boeing 737's end up as scrap metal usually at one of the desert bone-yards in California, either at Mojave or Marana, or possibly Arizona, at Phoenix, Goodyear or Kingman.

Google should find the companies concerned,

You should pay no more than scrap metal prices.
