I never bothered pluggin in my SPDIF cable in when I built my system or on of the firewirewire ports, I'll never use that firewire port and I also have a LCD poster display so is it really neccesary to plug in the system speaker?

nope - not if you don't want to

 

See this guy at work said it should be done, but I usually watch post anyway so I would see any messages anyway.

 

You only need it if you want to diagnose any problems with the PC powering on and no display.
You can decipher the beep codes to help diagnose the problem.

Although iirc MSI and a lot of other manufacturers did away with that by using an LED array to display the different stages of POST

So yeah its not really neccessary unless you are in this kind of situation, in which case just plug it back in

 

I just wanted as little cabling as possible inside the case so I had maximum airflow, plus I have an LCD poster that I can plug in if I need to.

 

As UKDarkstar said, you don't need them plugged in.
