I have been reading about PC building and since my parents and younger brother need a new desktop I have decided to finally build one. Since I am not extremely knowledgeable in the subject(I understand how things work, not sure what is the best combo and brands) I wouldn't really know if a build I have would work or not. I have a budget of ideally $750 but am willing to go up to $1,000- $1,200. I understand this isn't a lot and I can afford a lot more but since its my first build I thought I would be a little more conservative. btw, the operating system and peripherals aren't included in that price range.
My parents will just be using it to do minor work related stuff but my brother wants to play games on it such as Battlefield 4, Skyrim, etc.. I saw the following build from Forbes and am curious what could be done to improve what the writer came up with.
