Ok, so I have a Dell Dimension 8300 Desktop that basically got fried thanks to a power surge. It's pretty much been written off as a loss, but I was curious about using it as a chassis and building a new PC. But this is something I have never done before. So keeping in mind that it's several years old, can I find new components that will fit and work properly? Or are motherboards pretty brand-specific as far as what they'll fit in? Can you get ones with PCI slots, even if the PC wasn't designed for that, etc? I know I'm sounding like an idiot, but as far as computers go, I'm kind of an "out of the box" type person.
