Motherboard connection pins (PWR, HDD, LED)

I'm building two computers with PCChips m811 motherboards. The problem I'm having is connecting my cases to the motherboards. The plugs from the case are: 4pin speaker (2 wire - black and yellow), 2 pin power sw (2 wire - white and black), 3 pin power LED (2 wire - black and brown), 2 pin HDD LED (2 wire - white and red), and a 2 pin reset sw (2 wire, both grey).

The mobo pins are labeled as follows:
1: HD LED (positive)                  2: MSG LED [dual color or single color (-)]
3: HD active LED (negative)      4: MSG LED [dual color of single color (+)]
5: Reset Switch                         6: Power Switch
7: Reset Switch                         8: Power Switch
9: Reserved                              10: No pin

Everything fits except for the 3 pin power LED. I'd assume that it would go in the place of the MSG LED, but obviously 3 pins don't fit on a 2 pin connection. What can I do to make this case work with this mobo? I ordered the parts off the internet, so returning them and getting something different isn't really an option. Also, I found this post: http://www.experts-exchange.com/Hardware/Q_20228053.html, and I'm wondering how exactly I'd make something like the second option work. Can I just get a two pin connector and attach the wire from the 3 pin connect to it? Where would I get such a connector and how would I attach the wires?

Thanks in advance!
