In my experience Thermaltake cases are built badly, the metals are flimsy and the plastics feel and look cheap. I've never really used their coolers since there are other proven good options in their price range. If the only thing you care about is looks, then I guess Thermaltake is worth considering.

Woow, the materials look horrible. Isn't this is supposed to be a $130 case?

Get a high quality extension cord that is rated for high load devices like heaters and power tools.

Ryzen 5, easily. 

I agree with this 
Yes, for 8000 as well. 
I don't know if most of not, but there are quite a few AM3+ boards that were not designed for the 125W parts, don't list them in their supported CPU list, will struggle at full load and certainly won't handle any overclock without frying. 
I'd say go with $0 spending and stick to this rig, considering it is handling the games he plays well, and his only concern is CSGO which won't benefit from more cores.
OP, have you considered a mild overclock for your 4300?
Which clocks did you use the 6100 at? Also, you were going from Bulldozer to Piledriver, while for him it would be Piledriver to Piledriver, so no IPC gains. 
All in all, it's only the cache that will make a difference in his use case. 
 
Yes, it comes as in it comes inside the box of the Ryzen CPU
 
Mind you, I do support not overspending and even not upgrading at all if he's mostly happy with the current performance. 
I also think that, while the 1600 is great value, if all he wants is a small bump from his 4300,and if he decides to go Ryzen, he may want to consider the cheaper 1400 as well. 

The mobo he has only really supports CPUs with up to 95W TDP and the 8350 is 125W. It could work but I wouldn't call it stable and/or safe.

I'm not against background music in general. However, I don't like it when it is playing while Linus is talking.  It's kind of distracting actually.  This is a review, so the focus should be the reviewer's voice along with the visuals. Having music over the dialogue is just too much imo.  The music in the beginning was also too loud.
 
Less is more, folks.

I think in here background music is annoying especially as it is so loud. In latest channel super fun on vessel too loud music ruined the end for me as I wanted to hear the answer. Please don't make it regular or at least tone it down.
