I'm moving to another country and want to bring my desktop computer, but the assembled system is too large for my airline's carry-on limits. I've heard that transporting a fully assembled PC in checked baggage can be risky, especially because of rough baggage handling and heavy components pulling on the motherboard. I'm considering removing the case and buying a replacement after I arrive. Which components should go in carry-on luggage, which—if any—can safely go in checked baggage, and are parts such as a power supply or motherboard likely to cause problems during security screening?

Most ordinary PC components aren’t treated as weapons, but airport security has the final say and procedures vary by country and airline. Remove the parts from your bags if requested and leave enough time for an inspection. Also verify the airline’s rules for electronics, batteries, and checked baggage before packing.
If you’re leaving the case behind, disassemble everything and pack each major part in a padded box. Keep the CPU, RAM, and storage installed on the motherboard if they’re secure, then place the board in its original anti-static packaging and box. Put the GPU and power supply in their own padded boxes and keep the boxes from moving inside a larger suitcase or container.
Remove the graphics card before transporting the system. Its weight can put stress on the slot and motherboard if the case gets knocked around. I’d also remove a large air cooler unless it’s a liquid cooler that’s designed to stay mounted. Pack those parts separately, ideally in their original boxes with padding.
The graphics card can technically go in checked luggage if it’s very well protected, but carry-on is safer because baggage handling is rough. Check the airline’s size and security rules first.
Avoid checking an assembled computer, especially one with a glass side panel. Security screening usually isn’t the main concern; baggage handlers and impacts are. If shipping the entire computer is too expensive, transporting the parts without the case and buying a new case after arrival is a sensible compromise.
A recent international trip worked out with the motherboard, CPU, RAM, and NVMe drive in one carry-on, while the GPU and PSU stayed in their original boxes in another. Original packaging is ideal if you still have it.
