Full size PC with the cost/performance of a NUC?

[strikeout]

I am basically looking for a ~$600 box that runs on an I5. I figure buying my own PSU, mobo etc would cost more individually vs buying a pre-made. This will be for my wife who streams and does homework with our 11yr old.

This was the model I was looking for:
Intel NUC Kit NUC6i5SYH BOXNUC6I5SYH

Of course, I have to add ram, SSD and OS.

I see that NUC for $387 on Newegg. It's basically a case, PSU, motherboard and CPU. I'm not that familiar with the CPU (i5-6260U, a notebook processor), but I shouldn't think you'd have a lot of trouble duplicating or exceeding the performance for a similar amount of money. Somebody here should be able to say better. You're not likely to get it in such a cute little wife-approved box, though.
