I would love to see more standardization for consumer NAS builds. I've been asking ASUSTOR in particular for a few years now if they'd consider building a Mini ITX-compatible backplane/adapter, so you could swap out the backplane after a few years if you want. Or even Pico ITX or something, so you could swap in an SBC.

I hate that after 5 or 10 years, NASes can't really be upgraded. A lot of 1 Gbps NASes could be upgraded to 2.5 Gbps or even 10 Gbps if you could swap out the motherboard, keeping the chassis out of the landfill or extending its useful life.
