So I'm thinking of moving to the light side and getting into PC gaming. I'm either thinking of buying a ready built PC or building one. I'm leaning towards building one as it is often cheaper and you can get better parts etc.

Can someone look at this PC and tell me what you think of it: Customise PC | AMD Quad Core Power Gaming PC 8G, 1TB, R7 260X 2GB | Welcome to XP COMPUTERS

I will be mainly playing BF4 on it and maybe some other games.

I am also thinking of getting this mouse and keyboard: PB Tech - KEYCLM3010 : COOLER MASTER Storm Devastator Gaming Bundle - Membrane Keyboard & Optical Mouse ( Keyboard with Blue LED backlight , 2000 DPI Mouse)

I am wanting to spend no more than $1200
