The normal 2 LEDs are lit on the motherboard but that is all the system does now. No serial port data at all and I know my set-up works fine. The fans won't spin-up and the optical drive no longer initializes. There is no response to pressing the power button whatsoever. I did try swapping the power supply with a brand new Corsair RM750 that made no difference.
I managed to find my copy of the manual. If the two LEDs you speak of are the SB-PWR (standby power, green) and STANDBY (red), then that's the correct state when it's off. As with your X5000/20, the following LEDs should come on after pressing the on button:
- PLAT (platform voltage power good)
- C-A (CPU core A power voltage good)
- C-B (CPU code B power voltage good)
- DDR3 (DDR 3 voltages good)
- IO (IO voltages power good)
If that doesn't happen, then power to the CPU & other parts aren't being switched on. This means there's a problem with the power controller (or whatever it's called) that's supposed to power up the board when you push the button.** The sd-card containing the ROM may be perfectly fine; it'll never be read if the CPU never gets power.
Fault-finding beyond this point isn't what you'd expect the average user to do. It really should be looked at by a technician.
I'm a bit shocked that they still haven't helped you get it fixed yet.

** Or, there's a small chance that the power switch or cable is broken/disconnected, which I highly doubt but is always worth checking.
