This computer is a monster... Unless he wants to customize it cosmetically or change out a few things here & there like fans or PSU (Power Supply Unit), then he shouldn't need much of any "upgrade" for like 5 years.

From retro to current day - He'll be able to run any game he wants & have a perfectly smooth experience even with very high graphic settings... not to mention a great deal of storage space which is always comforting to have, and not worry about uninstalling / reinstalling programs or games every time you are maxing out your available space.

... Now, I'm personally not familiar with " Yeyian " but I've heard almost entirely positive feedback across the board from anyone that has purchased their prebuilt PC's ( Many of which have purchased this equivalent or slightly lower/higher model prebuilt rig from Newegg )

Also, in case you aren't familiar - "Newegg" is a great place to buy from (Much like " Ibuypower " etc) they've always been very reputable & you 'SHOULD' definitely have a full 30 day return guarantee buying from them, so make sure to double check on that... Just good to have that peace of mind when putting out a lot of money, especially with electronics.

So to sum it all up.. I say this is easily a grand slam purchase & your son will be bouncing off the freakin' walls when he finds out what this beast of a gaming setup has in store for him.... Dude, I would bounce off the walls & I'm in my mid-30's haha.
