I’m looking to make a new PC, and I’ve been left with two options.

1. Make a larger ATX build, plenty of storage for the hoarding?
2. Make that sleek ITX that I have been eyeing up and just purchase a cheap used workstation and fill it with drives?

For my needs it doesn’t need to be left on 24/7 so I’m not concerned with power consumption of the older Xeons, and currently I store everything on external drives which is fine but it would be nice to pop it all in one box, then back up. If you think the used workstation is a good option, any recommendations and one that can hold a fair few drives?
