Computer Build

My son expressed an interest in upgrading his computer, he's waffling though, as I told him he needs to pay for it himself.  He has the money, but doesn't want to use it.  I would pay local taxes to help out.
My goal was to keep costs down, but make it at least as good as what I have now. The one he has now is a handmedown from his grands, unfortunately the case is a propriatary dell with a propriatary motherboard, a normal ATX doesn't fit in it, so I can't use it.  I may be able to use the PSU, but need to tear it apart to do so.  I'm only planning on a 500W PSU as it seems power requirements have gone down considerably.
I'm going for AMD as it seems both the CPU & GPU are finally better for gaming for the price, not to mention they don't have the serious vulnerabilty intel does in the CPUs.
I'm not sure about the Mid ATX case (will it fit a tower fan?) or the mATX board, but I had a mATX board from MSI some time ago that I liked, and it saves a good $60.
The GPU I put separate as he has my old 960, so could do the rest of the computer.
Here's what I've got so far, did I miss anything, or anything else I should consider:
