Yeah, those are a severe pain. So many cables to connect.
Of course what made the installation such a pain was that I've never built a system from scratch before. I usually just get barebones boxes and transfer my old hardware. So I found myself having to do everything really slowly and carefully to make sure it was right.
But anyways, it's good to at least know a bad FD connector is rare. I've got a couple more hours to go here at work but I'll try your suggestions this evening.
Mucho gracias!
