Reddit mentions of NZXT CB-FRPAN Set 300mm Individually Sleeved Front Panel Connections Premium Cable (Black)

Eh not sure what's going on here as there seems to be a lot of conflicting information. You've probably figured all this out now given your post was 3 days back, but it could be useful for somebody else who stumbles upon this post:

• First up, here's a wiring tutorial for those who aren't used to working with 6 pin momentary switches. It's clear and concise with good pictures, should apply to almost any 6 pin switch.
  
  
• For those looking to purchase a switch, you want a momentary, not a latching one. A PC power button quickly closes the circuit, causing it to switch on. If you've ever held the power button down in order to hard reset the computer (without the reset button), you'll understand why a latching switch won't work.
  
  
• For connecting the switch to the motherboard headers, these made by NZXT are a great option. I used the white versions to hook up a vandal switch in my most recent build. They'll save you a good amount of time, effort and money when compared to crimping your own set. Of course, if you have crimpers etc. already, go ahead and make some from scratch, but if you have those you're unlikely to be considering a tutorial on how to hook up a power switch. Just lip off the ends of the wire that attach to the front panel and solder them to the switch instead (or screw in if you got a screw based switch).
  
  

I found this on amazon: http://www.amazon.com/gp/aw/d/B003ZDNXZI?cache=d1cdfe81669d1db2ed8b62758716668c&pi=SX200_QL40&qid=1412925427&sr=8-1#ref=mp_s_a_1_1

i found a way to use the front i/o it requires some cut&splice ordering long front panel extensions to do this amazon link nzxt product
and here is how to do it with PICTURES! diagram

FOUND WHAT I NEED aaaaaaaaand its sold out. cool.

I had this problem once with an OEM case and a new motherboard. I had another old case that I didn't want to use that had the individual front panel connectors. I figured out the pinouts of all the wires, removed the one large connector, removed the individual connectors from the other case, and manually wired up all of the individual connectors to the existing case wiring. It was a chore, though. Something like this could help: http://www.amazon.com/CB-FRPAN-Individually-Sleeved-Speaker-Premium/dp/B003ZDNXZI. You could either try using the male ends of those extensions to plug into the existing connector, or remove the existing connector entirely and re-wire it.

EDIT: If you really just need the system to power on, you can wire up a momentary, normally-open (N.O.) pushbutton between the "PWR SWITCH" pins on the motherboard. Very carefully and temporarily shorting the power switch pins with a screwdriver will also accomplish the same.
