Im building a gaming computer and I need a good case that's under $60 that looks cool, has good cooling, and preferably a Mid tower, as long as it can fit a ATX motherboard when i upgrade in the future. I liked the Cooler master 912 HAF, and the Rosewill Challenger, but both don't support front 3.0 USB headers that my Motherboard has, so idk if you have to have a case with front 3.0 USB headers for my motherboard to fit properly. I would prefer for the Case to be black with some LED's but its not a necessity.

This is the one you want: http://www.newegg.com/Product/Product.aspx?Item=N82E16811119274
It's mATX, same as your motherboard. And it's a very good case for the money. There's also a silence optimized version (Silencio 352) if you want to give it a look.
