OK. I probably wont be overclocking so how many watts do you think i should get, and is the rig fine?
a solid 500w with 34a on the 12v rail is fine for your build. look for more power on the 12v rail (and over all power) if you want to upgrade to a more powerful card down the road.
the antec eleven hundred also offers more room to build inside then the three hundred, don't know why it was brought up.
