Hello, I am a single dad with two little girls and want to build us a computer. Myself, I surf the net, store pics and music, would like an hdmi out to our 50" tv. The girls would use the computer for school work and possibly playing Minecraft. I have a keyboard/mouse and monitor. I have been reading everything I can for the past month but still dont have a "system" nailed down. Money wise, id like to stay around $500 give or take. Any help would be much appreciated, thanks
