Need Help w/ buying.....

Okay; so I've got all my parts picked out; I just need you guys to check for compatibility; and everything; also; I need you guys to give me some good suggestions as to a good Case + Psu combo.....[preferably no more than $90; cause I'm on a budget to building a 500 dollar pc....]...and you'll notice I added my own comments in parentheses as to my choices made; ....also; you'll notice that I've got a case + psu combo already listed; but I need you guys to check it out to see if you've got a better one to show me; or tell me about some errors/problems I'll have w/ the psu/case if I do end up getting it....thanks
