Crummy G5 Interior
I had to hunt a little bit before I found a metal polish that would safely remove the corrosion. Make sure you use a polish that specifically states it works on aluminum, or you can wind up doing more damage than good. I sparingly used a product named “MAAS Metal Polishing Creme” I bought at Wal-Mart, applying it, rubbing it in, and removing it using paper towels that came away stained black. Afterwards, I used some soft cloths to polish up. Today, my PowerMac interior looks almost new. But Apple needs to take a strong look at their manufacturing and finishing processes. This was a problem Apple could have designed out.
While I’m talking about the PowerMac, one of the things I’ve learned the hard way is to ensure that I put the PowerMac down on its back (in a horizontal position) when changing out video cards or anything in the PCI slots. If I leave the PowerMac standing vertically and then drop a screw, it tends to lodge in the rear fan assembly. It’s usually easily retrieved from there; but if you dislodge the fan assembly for better access to the crew, you now run the risk of dropping the screw into the case. I did exactly that but somehow managed to get the screw to roll into the very bottom which eventually let me tip the case forward and roll the screw into the very forward bottom of the case. There’s just enough room between the front end of the aluminum floor on which the forward fan sits and the front of the case to fish around and retrieve the screw. But I could have just as easily wound up with a screw I couldn’t retrieve. A loose screw inside a case is an invitation to play Russian roulette; maybe you short something out and fry the machine, and maybe you don’t.
