single beep from speaker, RAM counted correctly, three SATA devices detected [no IDE drive - so no OS yet].
If there are no bootable devices, you should get at least an "operating system not detected" sort of message - is that what you are thinking?
What's the boot order in the BIOS?
Have you got a floppy drive and bootable disk to test with?
Have you got an IDE CD drive to test with?
That's what I'd be looking at first - I don't trust this new-fangled SANTA, or whatever it's called!!
