What case you get is pretty much personal preference, try googling for any reviews that might point out any flaws in it and decide whether or not they're enough to change to some other case. Same for monitors, I guess. There's probably no major flaws in Asus' motherboards, that one has 2 PCI-E slots if you want to crossfire later on, pci slots and so on. And like I said, it's Asus, they make good boards. That GPU is probably one of the best budget GPUs (budget GPU compared to the 570 and higher). I can't say you can go wrong with that card, especially if building under a budget. You could consider the gtx 560Ti, though since you're going with an AMD cpu, going with an AMD video card is a wise choice, from what I've read. Dunno if it's just rumors. Doubt I have to say anything about DVD drives, even if I could... That PSU is good quality and 600W is just fine, I'm quite sure you could crossfire 2 6870s with a 600W as well. You could probably run it with a 400W as well, though that might be pushing it a little. RAM, maybe try to find a 1333 or 1600MHz kit if you can and it fits your budget. That CPU is definitely not horrible, but obviously not the best of the best. And yeah, HDD is HDD... SSD, there are probably cheaper alternatives you could go with, OCZ or Crucial or Corsair, but Intel is good quality as well.
