So the BMC is working fine... I even updated its firmware in the hope that something good would happen. In addition I:
24 pin power
4 pin power (one of two found on the Seasonic SSR-550RM)
VGA out
USB keyboard
IPMI / ethernet
heatsink fan
two DIMMs
Have I done something obviously wrong. If not then I'm trying to decide between:


- reseated the CPU
- booted with and without memory
- removed and inserted the battery
24 pin power

Have I done something obviously wrong. If not then I'm trying to decide between:
- bad board
- bad power supply (SeaSonic G Series SSR-550RM)
- bad or incompatible CPU (Core i3-4150 Haswell)
- bad or incompatible memory (Kingston 4GB 240-Pin DDR3 SDRAM ECC Unbuffered DDR3 1600)
