Well I would guess that if you had a functioning system before the "transplant" that your problem maybe one of the following:
1) the PSU in the new case is bad?
2) you have a stand-off that is not aligned with a hole on the motherboard that is shorting it out (if this is the case I hope you didn't brick the m/b)
3) you have something installed wrong
4) ESD Damage
So what I would do is pull this board out of it's new home and bench-test (observe ESD precautions and turn the PSU switch to the OFF/0 position while keeping the power cord plugged in....this gives you a ground to drain the excess electrons):
- remove all storage devices, extra expansion cards, etc from the m/b (except the graphics card)
- use one stick of memory
- plug your keyboard mouse into a white USB port (don't use USB 3.)
- remove all other USB devices
This should at least allow you to access the BIOS during the POST once you power-up your system. You can also access the BIOS by pressingh the "Direct Key" on the M/B (see your manual for location).
Keep us posted on your progress.
