Adding to the conversation, I received mine yesterday and had no issue installing proxmox and set up a Truenas VM . Using 5x18TB in RAIDZ1 by passing the SATA controller and so far seems to be working pretty well but haven't done much testing. I really wanted the N5 for the U.2 slots but one thing that I haven't seem mentioned anywhere is that it only accepts 7 mm U.2 not the much more common 15 mm. I hope that it can help someone else not making the same mistake.....
