Buy a KVM Switch [Keyboard, Video or Visual Display Unit, Mouse] which is a hardware device used for controlling multiple computers using single keyboard and mouse.

There are no standard KVM Switches for any kind of configuration and you need to first note down all your requirements before searching for the right device. There are not many online websites which are selling these devices but you can find a lot of options at Newegg.com.
