Nice, but 500GB is really not much storage...

Install Windows, update, install Steam etc, install a game or 2, drive is full..

(It's recommended to try and keep SSD's at least 10% 'empty' too)

true.  it's enough to get him started tho (he's 10).  plus now he can learn the value of working (doing chores, etc) to earn the money to buy an additional m.2 or SATA SSD to add more storage to it when the time comes.
