System build plotting update

Case i want: http://www.corsair.com/pc-cases/graphite-series-pc-case/graphite-series-600t.html
motherboard: http://www.tomshardware.com/reviews/z68a-gd80-p8z68-deluxe-z68xp-ud5,3025-4.html with a 2500K in it - the i7s are too costy I may watercool it with a cosair h60 as well
HDD: will probably pull the 500 gb off juno the dell - may go for an SSD later

video card: leaning towards a nvidia 560, but slightly bewildered by the varients
PSU: needs to be modular
ram 2x4gb (speed/type?) (4x4 seems the price sweetspot)
