This system is absolutely beautiful and in one of the most legendary cases! The Cooler Master HAF case was a fan favorite for many years and is very hard to find now. Pair that with a super high end Asus Z87-Pro and an Intel i7 4770 4C 8T and an RX 460, prepare to game on a budget! Wifi is included and Windows 10 is installed, tested, and activated. Power cord is included, original box not included. This system is perfect for heavy office work and eSports gaming!
