Decent $50~ Case?

So I have this i7-4790K laying around with an ASUS Maximus VII Formula and 32GB Dominator Platinum RAM, I was planning on building an extra PC with this, now I've looked everywhere for a nice case but all i've found is cheap steel cases, silver inside cases... Can someone tell me what's a nice decent case that's not made of cheap dentable steel for 50-60-ish? I'd prefer things like NZXT, CM, or something like that (I have way too many corsair builds, sidenote)

PS. Does anyone know of a good MINI tower PC? I'm also building a "throwback PC" and would like those cute tiny cases
