Fair enough.
Just making a point, top-end AMD systems are much cheaper and for basic internet surfing and music/movies shouldn't be noticeably slower.
Insert X4 980 BE instead of the X6 1090T and its the same price.
When my family shared a computer it was back in the "blazing fast 500MHz CPU" and "huge 100MB hard drive capacity" days.
I guess with 4-ish people today on one machine storing their own music/movies/files/programs 2TB isn't a huge stretch.
If he is happy to spend the money its a great build. I just keep an eye out, trying to help people save a buck.
