DVD burner and HDD both have a lot of complaints, if you actually did build that PC i would look around a bit first and see if anything better is available

Also, no GPU, id recommend (realisticly at least)
Either a 9600GT or a 3850 since both of those will play most things well, plus the next year and a half or so comfortably, at a decent price. Both are fairly equal in terms of power, so its more a choice of ATI vs Nvidia (or,c for those 2 links, $15 cheaper and the witcher :P
