Sorry, I left the builds on my list for a few days then deleted them assuming that the person I made them for had saved them by now so I didn't have a bunch of other peoples builds on my list but I can whip some together at some point today.
I remade my 3 under 1k builds in ATX, micro ATX, and mini ITX form factors. Here are the links. If you wanted to save a little more cash you can go with an RX 580 or a GTX 1660 video card which will do well at 1080p med-high settings, even not to shabby on ultra settings depending on the game of course. These builds are just what I would probably do if it were my money, adjust accordingly and enjoy.
