I am looking to build a PC for gaming only on my home theater system (essentially a steam machine). I am a total novice when it comes to computers and just a casual gamer. That being said I would like to be able to run most any games as the purpose is to have access to more games that what's available on my Xbox. 

Wondering if the attached build would fill this function. Any advise would be greatly appreciated. Also, if I am missing anything needed or anything on here would be overkill that would be great to know. 

Thanks for any help.

So the Ryzen CPUs that end in 'G' have graphics built in. In order to do that they sacrifice space in the cache for a performance hit. So, get one if you don't want a graphics card but if you are getting a graphics card, then you want the full performance Ryzen that ends in 'X'. Both the PowerSpec and your own list have selected 'G' processors and graphics cards. My advice is to switch to either the 5800X or 5600X for the CPU or ditch the graphics card.
