a good case for what? a case is personal taste. if your building your own custom bottom budget pc, i would not use that psu. get a recognised branded psu or it will break an take components down with it.
that case is too cheap, and you are even given a PSU with that price. that does not sound good to me.
what are you gonna use it for? anything more then a very low budget casual computer, i would say don't get it.
