I have a Dell desktop that my dad is no longer using and I still have to get it to work because when I start it up it loads and then a black screen comes up and says that i'm missing a file but I plan to take it to a computer repair shop. Anyways, you know how the Dell case looks and I want to get a new case and maybe one with a piece or so that is clear so I can put some lights in there and I just need to be pointed in the right direction and some of the steps to do. Any help or ideas?
