For me the distinction on Rimuru between 16 and 32 GB of RAM, has more to do with the my goal for the machine to last 10 years of service life. Centauri retired after 8, and I had designed it with 5 in mind.
So I decided to acquire two sticks of the same kind of memory, and fill the other two slots while it's still possible to get them. Actually, I think this is the first time one of my personal machines has had 4 largely identical sticks; only difference is the color to help ID the slots.
Well, now I have a pair of 10 Gbit/s rated USB-C ports in the back. Problem solved.
If I was a genius, I would probably put a C to C or a C to Micro 3.0 cable in the other port and route it to my desk/monitor area. Much as I have a USB-A 3.0 extension that makes it easier to hook up hard drives and Xbox controllers and such.
