So due to events recounted in this thread, I will need to replace the casing of my G5. And as also recounted in that thread, there's a good chance I'm going to have to pay for it myself. Which suggests to me that what I should do is buy a case off e bay and change it myself because otherwise this is going to get very expensive. How doable is this process? I basically want to move every component from the badly damaged case to a new one. Easy? Hard? Thanks!
