coolermaster makes some really good cases with the power supply included that may suit your needs at a good price,this link is in australia,so you will need to search for this product in your country if you like it
IMO, you would be better off getting a case that you like, but without the power supply. Then buy a power supply separately...ensure that it's 80 Plus Certified or better (I prefer Bronze as a minimum)....some cheaper ones like Corsair Builder's Series (CX V2).
