Pry marks on case edges

[mg.man]

I think I may have tighten too much my CRT and it made that little bump

I'm wondering if it might be down to your Mac's past life... there are actually two lengths of case screws:



I've found in the less adulterated (perhaps Plus and later?) ones I've worked on that the 'shorter' ones are used for the CRT and for attaching the internal frame to the case front. YMMV...

@MindWalker

the easiest thing you could try is some acetone and try to smoothen the edges, but don't use any plastic tool as it will melt too. 

Try this on a small dent first, should work.

Then there is my 512K, which I have no idea what was done to it.... 

the same thing happened to my Plus thanks to this nasty Ikea desk lamp.
