If your not going to overclock then this will work for youhttp://www.newegg.com/Product/Product.aspx?Item=N82E16835200036
Are you going to be upgrading your video card? Reason I ask, Sonata's are great cases but they don't have enough cooling to handle today's video cards. So you might invest in a slot cooler to help. 120mm tower heatsinks more then likely, will not fit in that case. So you need to stick with a 92mm hsf.
