Looks fine!

Your cpu will last you for a couple of years 😀

We have the same gpu card haha otherwise if you're planning to SLI then double check on the PSU if it's enough

Went with some slightly cheaper parts on this one:

As a note, I hope you have a storage drive and what not because there isn't one included in the build you linked.

As for the parts I changed, I just changed the PSU to something that's cheaper. It's definitely overkill and you'll most likely not even use half of it, but for the price, can't really say no to it.

I think you should just add another 2 more fans, as long the airflow in your tower is going in and out I don't see a problem.
