it looks like Packard Bell used a Intel based FP connector(hp did it then as well as did most OEM's)
Damn i hope this helps. While you can connect it all. it will be a pain in the ***. The standard is designed in a way that some grounds are shared. This makes it difficult to use new case connectors. If you wanted to make your own cable with joined grounds you can. But its easier to just get power and HDD led so you can see whats going on. That Packard Bell may not have ever had a Power LED or Reset switch anyway.
when will they all standardize.....
changed pic. It looks to be the same standard as the old K7S5A did...just with extra pins for IR and a Speed Button. tell me what you think? As for speaker. don't worry your board has it built in(buzzer)
