SOLVED Motherboard LEDs look OK but computer won't turn on

Just an update. So the motherboard made the journey to Supermicro and back. And it worked on the first try! The repair report states that they weren't able to find the reported problem but they updated the BIOS, IPMI, EEPROM and couple of other things. I was able to install FreeNAS with no issues. Thanks for all the help.

Glad to hear it. It'd be nice to know what happened, of course, but oh well.
