Moving the central processing unit
Moving the central processing unit
Keep the CPU in its slot, secured. It won't shift even if the case is dropped. Disconnect the CPU cooler and GPU. You can remove drives and RAM if needed, but they remain safely in place when installed correctly in the case or on the motherboard. This is what I did during a cross-country move. Remember, all your components traveled globally before arriving, so they're quite durable. Edit: yes, remove the cooler as you suggested—similar to what they do with suitcases at an airline.
Discrete graphics cards are the biggest problem when it comes to transporting gaming PCs. Tower coolers can be an issue but that's if you're worried about extreme shock. The dGPU problem can be solved by ensuring any force vectors like braking your vehicle hard doesn't impart force perpendicular to its socket. A CPU cooler properly mounted, outside of maybe the Icegiant Prosiphon shouldn't have enough mass to damage itself in anything other than maybe a full on high-speed collision, which you'd have bigger problems than a broken tower cooler at that point.
