Errr Jason, I am not sure where you got the idea Lynn wanted and AC power plug on the front of her PC?
I read her meaning as a couple of 1/4" phono jacks(?) for an aviation headset that works at funny/different impedance than standard pc audio amplification.
This is what came to mind for me: http://www.crutchfield.com/p_818EF2/HiFiMAN-EF2A.html?tp=48508&kw=&org=pla&nw=g&crv=19722308425
However it only solves the listening side, not the mic side of things, and wont fit in a drive bay.... But the tubes sure would look cool on top of her rig ;-)

>> In a nutshell, I would like to mod one of my 5.25" bays on my PC to house jacks that I can plug my aviation headset into. There is a pretty good difference in impedance between aviation headsets and PC audio. There is also a challenge in driving the electret mic in the headset using the PC mic input.
>> Bonus: If I can plug this modded panel into my motherboards front panel audio input, that would be awesome.
>> If anyone of you guys are good with basic electrcal circuits give me a shout. I can spring for dinner / beer if your willing to help. Hell, I will even be president for a Chugalug meeting if we can get enough folks together to discuss this :)
