It could be MB caps, PSU caps, or PSU anything else. Nothing comes on
when power is turned on, no fans, no leds, nothing. Same issue on both
hosts. No surprises there, they're identical models. It could be CPU,
but IIRC I already tried changing that.
The PSU part is vendor-specific. Standard PSU maybe could be retrofitted,
but that'd need some dedicated time.
