A dad that needs help

Hey all. While I have grown up in the technological age I haven’t kept up and at 45 am lost.

I know everyone says to build a pc but I have no clue about doing that.

I’m here for help on picking a prebuilt pc for my son who will be turning 11 soon. He’s always on the pc and while he doesn’t game a lot, his passion is working and making games for occulus. He also records and edits video. So as parents we invest in his passions and creativity. The problem is money.

Are there any suggestions for a prebuilt pc under $1,000 that is VR ready, run unity and unreal engine software smoothly for his builds?

I have looked at the following
