Unless you have a name brand case where you can go to the manufactures web site and download a schematic, your only option is to trace out the circuits.

Generally, the connectors are marked and you just need to figure out polarity on the LEDs.

The power and reset switches are momentary contact switches and it should be easy to use an ohm-meter to see which connector lines short when you press the switch button.

For the LEDs, use the Diode test function on a DMM and see which LED glows when you connect in the correct polarity.

Or, take the front off of the case and trace out the wires on the board.

Getting the actual case wiring is even more difficult than getting the schematic.

In fact, it may actually be cheaper to buy a new case.

Is the circuit board there, and you just need the wires?

Or is the circuit board and switches missing also?

I myself would go to the retail outlet of my local computer recycler and see what I could find.

Otherwise, if you can't identify the case manufacture, or they offer no assistance, I have found cables with LEDs, switches and other parts at surplus electronics firms like www.bgmicro.com and
www.allelectronics.com

I'm sure there are other sources as well.
