The ATX form factor (Advanced Technology eXtended) will eventually be replaced with BTX (Balanced Technology eXtended), Intel’s new internal PC design standard for combating the ever increasing power demands of components, such as processors and graphics cards. Despite all these increases in heat and power output, the demand for quieter working environments from the consumer is ever increasing. BTX will attempt to address these crucial issues.
