Painting a computer case
I've got a large gutted out pc case that's got that old beige look to it and was thinking about re-painting it black. Never did this before so I'm wondering if there could be a problem doing this. Also I was even kinda toying with the idea of coating the inside white for more light reflection, would this be a bad idea? Maybe the questions are kinda dumb but knowledge is power right? 

Of course I'll there won't be anything inside. As I said it's been stripped so I'm good there. I'm thinking a can of satin black rustoleum should do the trick. 
One thing I know about is painting prep. I have over 20 years in the painting business not to mention 8 years as a minaiture painter and exp. as a model builder. One question I have is how do I post pictures here? What format?
