Maybe I'm missing something but I don't understand the purpose or application of this. I have 200 TB in 4U. This has 14 TB, which is like 1 modern HDD. What's the goal of it?
Being mobile, affordable, while being DIYable? PoC? Nothing in there seems like the storage couldn't be exchangable for whatever is at hand, be it 'salvage', or brand new shiny SSDs if there are enough funds.
Whatever. I liked it.
