I recently inherited a Dell Dimension B110 from a pretty heavy smoker, formatted the hard drive but getting error messages installing Ubuntu due to all the cigarette nastiness covering the fan/inside of the computer. Yes, I found the directions on how to open the case for this particular computer on the Dell website but the case just is not sliding off like it says it should. I'm pushing the button on the back and pulling on the case so hard my fingers are bleeding and it just won't budge. Is there some sort of trick I can use to get the stupid thing off? :emotion-9:
