Looks like a nice build . I personally use Intel , so cannot advise on the AMD kit . I would say to try and source a 7200RPM HDD , rather than the slower 5400RPM you have selected . The Samsung SSD is awesome , fitted one recently , and with the rapid tech activated OMG ! so fast it will melt your face off ! I do advise trying to source your MoBo , CPU , Cooler and RAM as a tested bundle from one supplier , who will overclock for you . Good luck !
