 Enthusiast computers (often referred to as a "box", "build", or "rig" by their owners) commonly feature extravagant cases and high-end components, and are sometimes liquid cooled.Although high-end computers may be bought retail in the same manner as the common computer, they are frequently assembled by their owners.Enthusiasts assemble their systems to simply enjoy the best images and effects a new PC game has to offer, to design an aesthetically pleasing PC, or even simply to obtain the best possible performance at a variety of tasks.
