Yeah Craigs build is a way better build.
I'll add that cases are very much a personal opinion. If your son wants a power house PC that also looks like it has some horse power, i think he will be disappointed in the case Craig have chosen. I'll choose something else.
What about this one? It's 20 bucks more. But looks like it cost double as much

Also note that while the system has been improved (and decreased in price. good job craig) the power efficiency has decreased with that Power supple.
You are going from an impressive Platinum validated PSU down to a only bronze.
The PSU he chose is not bad at all, but it's just nothing compared to the one you chose before.
How about this one?
it's a gold validated PSU. It looks much the same but it has an extra 50W and is Gold Validated. That for only 15 bucks more. Well worth it.
