The life expectancy for the Samsung PRO is at least 2 times of the EVO in the same series line like PRO 970 to EVO 970, but the
EVOs are good enough see

The PRO is a better choice if plan to deal with BIG files like when editing video because there will be no cache(SLC NAND) starvation.

I prefer AMD GPU, can be a RX 550/560, see

But for DAW stuff you can be just fine with the integrated GPU.
The cooler seems OK

IF plan to buy a 6 core CPU need a compatible motherboard, ASUS PRIME B250-PLUS is not...
In the USA the ASRock Z370 PRO4 is $15 more than the ASUS PRIME B250-PLUS, but it is a way better motherboard with Thunderbolt header, Intel NIC, stronger VRM and compatible with 6/8 cores CPU, but for 8 cores I would choose the Z370/Z390 Taichi.
$250 for the 6 cores i5-9600k is sweeeeeeet!!!!!!!!!!!!!!
Sadly only the i9-9900K or i7-9700K have a soldered heat spreader.
