software and can be purchased or otherwise acquired for a reasonable price. But that's solid modeling, not to be confused with Surfacing software. For good surfaces you need a surfacing program. I think 3D Studio Max and Rhino are good to start with, though I've not used either. I use Alias exclusively, but it's expensive ($10k+ for a single seat), takes a long time to learn, and you need a good graphics card to keep it happy.
Keep in mind that the most difficult step in making 3D data is finding a place to start. In the case of a screen bezel you really need the data for surrounding parts, and this is quite impossible to get.
