While most of your suggestions were decent, I would never ever ever suggest building a computer around a sh%tty PSU like a rosewill unit. The PSU is literally the heart of the computer, pumping the necessary juices to all the vital organs. You don't want a PSU that does a crappy job of supplying your primo hardware with rippled/unstable power.
In *my* honest opinion, sell the blood to get the better PSU. Nothin' like investing in 1500$ worth of hardware to have something crap out on you because you picked up the bargain barrel PSU.
