Just a quick note to say I have had a rather catastrophic power supply/hardware failure here, it has taken out my workstation, the internal RAID, the external RAID, my Titan, Motherboard, Xeon CPU, SSDs and pretty much everything that was plugged in at the time. Chips blown off drives, tracks burned off the motherboard, it is a disaster.

… I am currently deciding whether to take it as a sign from the gods and bow out of the hobby, or start over.

As Jason once bitterly complained: “The gods want their entertainment. The gods are cruel! In time all men shall learn to live without them.”
Or Conan's sage philosophy about the gods: “So grant me one request. Grant me revenge! And if you do not listen, then to hell with you!”

BTW, as a snub to the gods, your hard drives may still be salvageable. It’s only the electronics that were fried, not necessarily damage to the platens, too. It may be worth the gamble/expense to have the drives platens physically moved into the working case of an identical drive (same make/model/controller-chip) in a “clean room”, of course.
