Ok. So i ordered this case http://www.newegg.com/Product/Product.aspx?Item=N82E16811322016 and this power supply http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016 but the power supply is just a tad bit to big, and I have no clue what power supply to get now, I thought they were universal in size wise, unless I have a micro PC, or mini. But for regular mid towers i thought it was universal. So I need help finding out what power supply with about 500w-600w would fit into my case. Thanks for your help.
