Business PCs, Workstations and Point of Sale Systems

Transplanted an HP z420 into an NZXT H500i case. Got it powered up, boots ok, but have some errors. Here's what I'm trying to sort out.

-Not connected errors
Front USB 3.0
Front USB 2.0
Front 1394

FireWire is easy fix, I'll plug it in and hide it in the lower portion of the case, it never gets used. The front USB, the 3.0 and 2.0 stock cabling wasn't used because the original cables were too short, so I'm assuming I need to find either a way to extend them or a way to make the front panel ones from the case work. I need the 3.0 to work. I think I read somewhere where the 3.0 piggybacks off the 2.0 for some reason, can't find that article anymore.

-Other issues
Ambient Temperature Sensor

Fan Speed is good for about 90 seconds, then the jet gears up for takeoff!! I've got the front and rear fans connected, as well as the memory fan, but they ramp up to full speed and I believe it has something to do with the ambient temperature sensor. It's hooked up (I hacked the original connector until I got the individual pin headers I needed) with the ground, but I'm not sure why it's ramping up.

I'll try and get pictures of the setup in it's current state later and figure out how to add them.

Any help would be greatly appreciated.
