What is the most reliable way to connect this case that has the 80W PSU in it to the P1900. I do not what to cut my AC adapter cord (usingi it for inside testing etc). Should I use your suggestion for the AOpen case or is it a diffrent cord. Also what is the better way to setup the ACPI connection? Use the JP3 option or the output on the J2 pin 8. also what ground do i use to combine it with the green wire output from the J2 pin 8? help I have checked the MP3 forums but no specific answer?
