Thanks. Just ordered one.Yes, you can run an nvme SSD off it easily enough with the right adapter.
You only get PCIe 1X speed so it's limited to 500MB/s but that's a small price to pay for more storage.
My tiny Proxmox node uses the small 16G ssd that comes with it is the Proxmox OS, and the 1TB nvme is a zfs/gluster setup for shared storage.
I have another Wyse box as the proxmox quorom device and gluster arbiter
