some of these NAS operating systems run off USB flash. The OS is nothing really.
switch from dGPU to iGPU

you are building a home server NAS with chinese characteristics? Xi the Pooh bear will be pleased.
thats new to me. Maybe you need to go into bios and disable it before removing it?
lol I got the number wrong too when I was typing this reply: I do use RAID1 on my server with three drives in RAID1. The reason I do this is because I already have the drives (I buy a new one when the warranty expires).
 

bro use Red Flag linux for your Chinesium build, and you must live stream the build playing soviet music.
It helps when installing the software and setting up networking. I see no harm in leaving it in there, but maybe it will waste a little power? - i dont know but i think it will waste a little.
dont raid0 an SSD OS drive. No point. I dont use freeNAS, but a basic debian server (that I use for pi hole) is only 1.2GB. And I could reduce that if I could be bothered. I'm sure FreeNAS is also under 5GB.
 
 
 
 

There are some low profiled RX560, which is more powerful than 1030.

You can strip out the dvi port if you want to you know.
