well, i mean pretty much any non-mini itx case will fit that system. so you're sorta casting a wide net.
it will come down to the features you want i think, and how it looks. cause pretty much every non-mini-itx case is in play with that build.
I feel a standard atx case should suffice. You want the best cooling solution for your hardware when choosing a case I believe. Though it depends on what size and where you are going to put it. I honestly wouldn't use anything small for a i5 and graphics card, slim cases tend to be inefficient in cooling.
