looks good! I got the same mousepad, keyboard and monitor too.
And that's a lot of heatsink in one box.
I recommend a Z370 board from msi and i3-8350K with a 120mm Aio cooler and a 1060 for ant future upgrades. Also 8gb is fine for a while but it be nice to upgrade to 16. lastly mabey a few more case fans to improve airflow. But perfect pc for a first build A1 my man
