Keep in mind that it's just a rough outline. Case/SSD/HDD should be changed according to taste/needs and there's lots of interchangeable options for mobo/RAM/PSU so the choice depends on whatever is in stock and cheapest.

The jury is still out on 9600K vs 8600K. The 9600K is soldered but the die is so thick that it's not actually cooler while delidding became much more difficult and to get the full benefit you need to sand down the die.
Until we get statistics that it actually overclocks better than the 8600K I'd assume the worst.
You're willing to spend more on the cooler than on the mobo? Either way Aios are really not that impressive.

And no, nothing has changed since that rant.

Yes, that's just 4 cores (with HT though), but it doesn't change the fact that the Aios are getting their asses handed to them by Le Grand Macho RT, a fucking single tower single fan 60€ cooler.
Basically no reviews include Air coolers in the Aio reviews because it always makes the Aios look laughably bad, struggling against coolers that cost half or less at thrice the noise level.
Even going to 6/8 cores doesn't change much, while the single fan Grand Macho might drop off adding a second is cheap and this is the point where the dual towers like the NH-D15, R1, TC14PE and so on start beating the single towers like the NH-U14S because before that the second tower didn't even make a difference. It wasn't even necessary.
So either get a good air cooler or go straight to semi-custom prepackaged sets for proper watercooling instead of spending 40$ more than for an air cooler just because you can't live without being able to see your RAM from all angles.
The cheapest mobo might do everything you need it to do, except overclock. The lowest end uncooled/unheatsinked 4 phase VRMs will not get you to 5 GHz, let alone 5.2 GHz. You need a good CPU to get past 5 GHz, which is luck of the draw, but you need at least decent VRMs to even get to 5 GHz and there's no luck involved in VRMs.
When did you look up the RAM? For that price you should get higher frequency and/or better timings.
There are multiple options along the line of price/performance tradeoff, but we can leave the SSD be for now.
The PSU makes sense and there's nothing wrong with it, it's technically flawless, it's just not any cheaper than all the better options. EVGA G2, Corsair RMx v1 and Seasonic Focus Gold are simply better. G3, RMx v2 and Focus Plus Gold are much better. And none of those cost more than 80$ either. The G2 actually costs the same and the G3 right now costs less than the G1+. Until EVGA sorts out their MSRP the G1+ is basically pointless.
Sound cards are complicated. Depending on your headphones/speakers I'm not sure it's worth spending that much.
What's your current CPU? Removing the game load from the CPU only does so much, so I'm not sure you'll be able to stream at "significantly higher quality".
