I recently bought a HP 6300 elite SFF (small form factor) motherboard to put up a server in my workplace. So I don't have the HP original chassis and as you know the motherboard will display this messages at the startup:
917-front audio not connected
921-front usb 1 not connected
922-front usb 2 not connected
512-Rear chassis fan not detected
F1:boot
Like this:

So the server won't boot up unless someone presses the F1 key. That's just stupid right? the bios setup has an <<<option>>> for this but it doesn't do anything! the problem goes on!
The solution:
For the first 3 errors just put a jumper in each header like this:

it will look like this:

As for the last one (512-Rear chassis fan not detected) what I did was simple, i took the sense signal from the cpu fan (the green cable in my case) and connected it to the rear fan header with a jumper cable like this:
