It doesn't come with a PSU, and -see to be honest mate- the PSUs that come "free" with cases tend to be very low quality -regardless of wattage-. There's every chance that a low quality PSU will go up in smoke one day, taking most of your components with it. Go for a decent, branded PSU from the likes of Tagan, Enermax, Corsair, Antec, etc.
I'm also not too sure about the case. If you're in that price range, there's no real substitute for a nice Lian-Li PC7. Those 25cm fans on the value case are just silly and tacky.
