ckbone, yes I'm starting to think the same thing, but the separate amp on it and what looks like better components than what's in the io keeps me wondering.
My IDE cable routes out through the memory door. I cut off a curved corner from the door (dremel'ed it nicely) and split the cable at every fourth wire. The wires for the speakers run out through the second USB port, but they may get routed thru the memory door as well since I may put a second USB on there.
At the base, the IDE cable is flat again and it goes in the back of the case between the bottom door and the case. I again dremeled a small notch out of the bottom panel so you wouldn't even notice it when the case is buttoned up.
The speaker wires go in through the empty game port. That's going to change.
I just wanted to get things working for now, I have other projects on the fire I'd like to get cracking on. I can neaten this one up later, when I decide to either use or toss that board.
