Water Damage TrueNAS Mini XL+

[barnacles]

I awoke one morning recently to 2 inches of water covering my entire floor. In the line of fire was my TrueNAS Mini XL+, which no longer powers on.

I have tested the power supply, which seems to work when plugged into a testing device, leaving me to believe the problem is somewhere with the motherboard.

Can somebody please help me offer advice for getting this machine back up and running?

I assume my data is ok, as the bays should have been above the water line, but I guess I will find that out once I get the machine to power on again.

Should I be doing a full motherboard swap, or testing individual components? What tools would I need to do that?

I'm not completely new to building computers, but I was never an expert and it's been many years. Besides, I don't know much about the parts used in the TrueNAS products. All help is deeply appreciated. I have both personal memories and work documents locked away. It's been a challenge, especially with all of the other water damage sustained in the house.

Below are the specifications for my machine. I upgraded to SCALE, though that's probably not relevant to the hardware issues.

Thanks for taking the time to read through this.

Anybody have some ideas?

Did the PSU get wet? If so, I would not trust it, its isolation may be compromised, which may make it unsafe (to the server or to anyone touching the server).

Should I be doing a full motherboard swap, or testing individual components? What tools would I need to do that?

I would first make sure everything is 100% dry, that includes all the connectors - especially the DIMM slots, remove all DIMMs and verify they're dry and clean and that their sockets are dry and clean. Disconnect the disks and test the motherboard and RAM with a new PSU.

If the system powers on, it should be safe to proceed and you can plug in your disks again.

If not, the only real replaceable parts are the motherboard and DIMMs (and the NIC, I guess, but that is secondary). I understand it's a (lightly customized) Supermicro A2SDi board with a C3758 SoC, so that would probably be the replacement you want - but note that you will lose some features exclusive to iXsystems hardware unless you go through them. It's possible that you can get away with your current memory even if the motherboard was damaged, but it's very hard to provide specific guidance in the abstract. Illustrations would be welcome.
