OK. Back to electron wrangling. Go in early thanks end of Daylight time.
Checked out power supply and have power/voltage on 20+4, 4 ATX and SATA.
Still no dice? No fans, CPU or case from case header, and no other signs of life, except for the power LED. Didn't have time to check amperages, only voltage.
Next plan is to temporarily try the second power supply.
For F1, I prefer the mid-late sixties and early 70s, rally, all 70s. Watching the great ones blast over roads I'd run (one hell of a lot slower) was still a blast.
