Server Rack Batteries For DIY Power?

Ran across this video which discusses the newer use of batteries typically used for computer server banks to set up DIY battery banks versus using raw batteries. I guess server rack units have a bunch of add ons, that make using them and setting up the battery bank easier, and the cost is nearly down to raw cell prices.

Why are people NOT buying raw LiFePO4 cells?

Any thoughts?

I think I will share this with my electronics savvy brother who has been maintaining the off grid electrical system at the family cabin. I don't have the knowledge to know how to set up such a battery bank to my own grid tied system that could be used to support a couple of freezers and phone charging.
