Oh, different story then if you're willing to repaint the whole thing. I've got an SE/30 that's REALLY yellow. I was going to try to whiten it but I doubted I could really fix it so I'm going to paint it silver and gloss black to match my iMac. I painted a DVD drive to match the iMac using Krylon brushed nickel spray paint. It's darker than the iMac but the closest thing I could find. The cap on the can looks a bit gold-colored but the paint isn't.
But the SE/30 doesn't work. When I switch it on the fan hesitates a bit then starts spinning but nothing else happens.
