Update for my situation:
Bought a new case tonight at Fry's for $20.00 because I was sick of dealing with my stupid Dell case. Even though this new one is a cheap case, it came with all the front panel wires divided up and labeled clearly, so all I had to do was arrange them according to the standard configuration. Everything booted up just fine. Now gotta get an OS so I can get all my drivers installed and start playing World of Warcraft 😀
twitchee, good luck with your problem and I hope it works out for you!
