Under certain circumstances, those iFixit places are exactly what it says on the tin - but if rent's coming up and they haven't had many walk ins, you might end up with a new Flux Capacitor in your JavaScript Microlibrary, since the old one looks like it started sending unhandled exceptions to the teraflop reader - but don't worry, they put in a new 6-charge teraflop reader that should future proof it for years.
