Microsoft Sidewinder x4, logitech g400, LG IPS234V, and really cheap wireless adapter and dvd, and also what case should i get, either the NZXT Phantom or the Cooler Master HAF X, i dont mind paying a little extra for the Cooler master if its better, i plan on putting a decent cpu cooler on later, probably.
You can get HD 7970 Ghz edition. A SSD is a must nowadays for faster boot times and R/W transfer rate look for Samsung 840 or 840 Pro. WD caviar blue or black whether you're going with SSD or not or you can get Seagate Barracuda.
HAF X is a high end case for maximum airflow. That power supply seems to be unknown to me, get a quality one from Antec, Corsair or Seasonic. I prefer Corsair HX 750W modular.
You won't gain anything from getting a RAM faster than 2000 MHz, the differences are very nominal. Still 1600 is the popular ones.
