I'm researching components for a new build, and have found some cases that I'm considering, but some still only have USB 2.0 on the front. Is it possible to swap those front USB 2.0 plugs for USB 3.0 plugs after purchasing the case? If so, how much does something like that cost? If its not really cheap, its probably not worth the effort vs spending a little more on the case to get one with USB 3.0.
