A few questions about replacing a PSU with few variations.
So I've spent a lot of time the last few weeks browsing these forums, searching the web, watching eBay, and asking around locally. I am still torn between forking over the $150-$200 for an eBay replacement or trying one of the adapters (

First off, I would like to get a little insight into my problem, to make sure I'm diagnosing it correctly. Two weeks ago I went to turn on my trusty 1GHz FW800 to type a quick document for work. I have been using this machine for over 6 years, without a single problem. The only modifications I made to the machine in the first few years (besides OS updates) was 3 sticks of memory, and another 60gig HD. Two years ago, I wanted to update my vid card to try and squeeze a few more years out of the machine. I went with the ATI 9800pro 128mb card. In order to use my Studio Display with this new card, I had to purchase the DVI to ADC Adapter with it's own power supply. Everything was peachy.
The other night, I pushed my power button, like I've done thousands of times before, and the button lit up like usual, but I didn't hear a fan or any noise coming from the machine, and the power button slowly faded. I then proceeded to push it again, and this time nothing...no light, no noise. And this is how it currently sits...
I've done pretty much everything I can think of to figure out what's wrong. I've tried unplugging and re-plugging, replacing and testing the power cord, using a different surge protector, using a different outlet, resetting the PMU, replacing and testing the battery, and reseating my memory sticks and graphics card. When the machine is plugged in, there are no red lights that glow. So, I followed the PSU test using a multimeter. I removed the black connector cover and stuck the probes in as best I could to get a reading, and I could not get a single reading from the first step of the PSU test. Am I safe to say my PSU is shot? Or...should I get some kind of a reading even if it is shot?
Lastly, I've read that one of the drawbacks of using an ATX PSU is that I will not be able to use my Cinema Display. With my current setup, using the DVI to ADC Adapter with it's own power, will it be possible for me to continue using my Apple Cinema Display if I were to use an ATX PSU? Thanks in advance for any insight/advice anyone can give!
