I'm finishing up an iCade to PC conversion and am looking to do the same. I'm wondering what artwork you chose or created? I'm having trouble deciding what to do with mine.
I peeled the sideart off and sanded it. It mostly came off very easily, and only minimal sanding was needed. I've painted and sanded a nice black finish on it, but I don't think that's needed. Right over the existing artwork is probably your best bet.
