The potentially free render nodes don't have NVMe slots, so buying nodes for that would unfortunately would immediately raise the capital budget by quite a bit. ...although we do have a smaller number of nodes with 4-6 NVMe slots each. So then the question becomes: 8-24 nodes with 1-3 SSDs each, or 4-6 nodes with 4-6 NVMe drives each? > Those chassis can even only have their server trays partly populated > too.

I did look into that, but unfortunately 4-6 chassis is probably the most I can reasonably make the case for.
