super computer
The fastest and most expensive computer would have to be a homemade computer. Not a brand you can buy all ready to go. Some homemade computers can cost a total of over $10,000 when fully modded.The fastest and most expensive computers are always the ones called Supercomputers. These currently compute in the petaFLOP rate and usually cost from $10,000,000 to $100,000,000. Some are commercially available, some are custom built to a contract.

According to TOP500, the fastest computer is currently (as of September 2017) the Sunway TaihuLight, at a speed of 93 petaflops. I don't know whether this is also the most expensive computer.
The fastest would be the most expensive computer right out of the factory, then overclock it to make it even faster, would probably be the fastest until the next computer was made from a factory to top that. Try Alienware computers.
Currently, China has the fastest computer
