So I have been a collector over the years and on a whim decided to buy a display case. So I purchased a simple Counter Top case, at least that is what it looks like from O-Review. I have a couple of questions about my case and additions to it. 1. It came with two clear shelves, but I also noticed that on the top and bottom in the middle of the case there are 4 screw holes. Just wondering what those are for? 2. Having never used a case like this before, I was wondering what people do about lighting. I would like to have some lighting at the top, but I am not sure if Oakley had something in those cases (maybe that is why it has the screw holes at the top), or if there is a good solution for that. I just think it would be nice to light up the case. 3. The metal has some spots at the top, I was thinking about trying to polish some of the dark spots out, but would that ruin the X-Metal finish on it? Thanks for any help or advice!
