Personaly I kept my old 386, the same machine I played WC1 and WC2 on back in 1992. And Privateer. Anyway, that machine is sitting under my desk, plugged through a KVM swtich* to my main monitor, keyboard and speakers along with my new PC.
* A KVM (keyboard, video, mouse) switch is a device that allows to plug two or more PCs to the same set of input devices, effectively allowing you to use a single keyboard, monitor and mouse to use multiple computers. Some KVM switches even share USB devices and sound.
