This case is the same price range, has a discount code currently, and isn't plastic. It looks to be the same body as a Rosewill Challenger but I am not sure.http://www.newegg.com/Product/Product.aspx?Item=N82E16811121096&cm_re=blitz-_-11-121-096-_-Product.
It is $30 without only $2 shipping, instead of the $35 + $20 shipping charge on the other case you had. On such a tight budget I can't see using 5%+ of the entire budget on shipping for the case.
The one you listed has a couple more fans but that is easily fixed by grabbing a 4 pack of them for about $10 later ($15 for blue LED ones) on if the rig is getting hot, which it shouldn't with the other parts you have.http://www.newegg.com/Product/Product.aspx?Item=N82E16835200061&cm_re=rosewill_fan-_-35-200-061-_-Product
