I need to cut a rectangular hole in an aging, slightly brittle A500 case, in the back next to the joystick ports. What's the best way to go about it without damaging the case? Dremel router bit? X-Acto knife? Soldering iron?
Hahahahaha!
I did use an old soldering iron to melt a semi-rectangular hole in the back of the case for a flicker fixer video port. Cleaned it up with square corners using a flat file to make it look professional, , then superglued a trimmed down PC slot bracket with a VGA cutout already in place. Looks like it was part of the original manufacturing process. I would assume a series of drill bits to gradually increase the hole size could be used instead of the soldeing iron. The plastic files away fairly easily to clean up the hole for more square corners.
