Don't get any video card for that machine. It's really not worth it at all, and I mean it. You could get a complete used system that's better en general for less than what a decent GPU could cost you that fits that case. The 1030 will fit and the power should be enough, but it's just a waste of money as it's such a bad card. And your pc is too old by now, I wouldn't suggest spending money in it. You'll end up regretting the practically null value you'll get from buying that gpu or any other that won't take advantage of it because of your other components.
