So I failed to realize that I need a PCIe to M.2 adapter: SABRENT NVMe M.2 SSD to PCIe X16/X8/X4 Card with Aluminum Heat Sink (EC-PCIE)(https://adv-traveler.com/7786/links/281831/sabrent-nvme-m-2-ssd-to-pcie-x16-x8-x4-card-with-aluminum-heat-sink--ec-pcie-) I came across some sites that mention some users of these old machines are having trouble getting it to boot from an SSD. We'll see if this works.
