That's a pretty good case! Especially if your doing just minor gaming. It should have good ventilation. What kinda MMO's are you playing? by the way that is not a PSU combo so a PSU would be a good investment.
This one is good if your not on a tight budget http://www.newegg.com/Product/Product.aspx?Item=N82E16817171036
This one is a bit more budget friendly but is not modular, and your case that you have does not have very good cable management so modular would be worth your money http://www.newegg.com/Product/Product.aspx?Item=N82E16817139019
lol actually for some reason i thought that was a case/psu combo
now im sad lol about 60 bucks is my limit. But i was thinking of just getting that case and then using my current psu. but i will keep looking for a good combo hopefully my local PC store which is terribly expensive will have something i can use cuz my mobo and cpu will arrive in a day or two
