Right at 1K with the operating system. Mount the extra 200mm fan in the front of the case as input, and move the stock front fan to the top back as output. Good price on the MB and CPU combo. If you play some of the newer games like guild wars 2/planetside 2 a overclocking processor makes a big differance in big battles FPS wise.
