In about the $500 range (i'd say about 400-600). Now, it doesn't have to play Battlefield 4 at max settings with 150 fps. I'm just looking for a pc that will play just about anything at medium settings with little to no lag. Games I know i'll be playing that come to mind are Minecraft, DayZ, Killing Floor. I doubt i'll be playing things like Call of Duty or Assasin's Creed.
I know next to nothing about this sort of stuff, so I need it to be pre-built, playable right out of the box, and in that price range (if there's really nothing that works like this then of course i'll go higher, but obviously I want it as cheap as possible).
*Oh and preferably have Windows 7*
Right now I was looking at this one: http://www.amazon.com/...00D1KX2M4/
