Hi,
I have bought a Asus p4p800 deluxe and a Coolermaster Centurion cac-t01
case.
The front firewire connector doesnt fit into the mobo? Yes it is the same
connector but 1 pin is blocked so it cant pushed in.
The dealer say, yes ist normal, sorry but use the backside firewire.
Hmm is that so or other solutions?

This is the manual for the case. It is a large GIF file.
The Firewire connector seems to match the 1394 header information
in the P4P800 Deluxe manual.

So, even with the "block" in place, it should still line up with the
nine pins soldered into the 1394 header on the motherboard. The 1394
header is red in color and is located near the bottom edge of the
board, in the center.
The difference between the two pinouts, is the pin 10 on the Asus
motherboard is GND and pin 10 on the case is NC (no connect). Asus
put the GND there for use if there was a shield foil on the cable,
and if there is no shield, it is OK for the case to simply NC the
connection. Some cases will connect all the shields of the case
connectors in some other, sneaky way, so if you were concerned, you
could use an ohmmeter, to verify whether or not the shield of the
connectors is joined to the rest of the case metal or not.
Since case manufacturers are notorious for getting connector wiring
wrong, it pays to at least verify that the power and ground pins on
the firewire connector are correct. You could, for example, trace
with an ohmmeter, that the appropriate pin on the case 2x5 connector
goes to the correct pin on the front of the case. Bad things would
happen if the +12V or greater on the power pin, were connected to
one of the four TPxx pins. Since most Firewire devices are expensive,
a little detective work now will save you having to get your Firewire
device repaired later.
Here is the pinout for Firewire according to an Apple Computer hardware
manual (as Apple invented Firewire, AKA IEEE1394). Page 34 gives USB
pinout, while page 37 has Firewire pinout.

Here is another picture of pinouts...

Looking into the firewire connector on the case, this is what you
should see. You want to make sure the PWR and GND pins are what they
say they are. Nothing would get fried if the TPxx signals are mixed
up with one another.
