Of course it doesn't come with a cpu
It has an AMD FM2/+ socket, if you were wondering.
Yes you can find a really cheap case for it. Its an ATX mobo so you can find fairly cheap cases for them on newegg.

It doesn't look the part, but that's what you get for the price, right? If you have a bit more cash on hand, go for a corsair branded case, in my opinion there the best looking cases around for a decent price tag
