Switched in better motherboard(thermals).

Storage doesn't make any sense, unless you are buying that 256G SSD for an emotus fusing with the HDD. Even then, 1TB HDDs don't make much sense and I'd look for something like the 4T Barracuda compute (although maybe not that one, I'd avoid Amazon HDD buys).
Note that I do use the emotus system, except that I just happened to have a 256SSD and a 2T HDD left over from my old system and use it for a steam library (so backup is irrelevant).
I was considering the smallest to be a dedicated boot drive. HDD for majority of storage needs. SSD for gaming/music/programs. I’m not planning crossfire. I like aesthetics and large cards are a hazard in my opinion.
PS: sound card? Doing some rather specific audio work? They are rarely needed anymore.
