I'm taking my desktop PC from Canada to another country for a vacation lasting a few months. To avoid expensive shipping, I'm considering removing the components and packing them in my luggage, then assembling them in a PC case I already have at home. The parts include a motherboard, RAM, GPU, power supply, CPU cooler, case fans, keyboard, and mouse, but no monitor. Could traveling with these used components cause problems at customs, and might I have to pay import duties or taxes?

Customs rules depend on the country you’re entering. Even if the parts are used and no longer in their original packaging, they can still count as imported goods. Keep receipts or other proof that you already owned them, check the destination’s temporary-import rules, and declare them honestly if required. Don’t assume removing the boxes eliminates possible taxes.
A practical approach is to leave the case behind and buy or use one at your destination. Carry the GPU, RAM, motherboard, and storage drives with you, while putting less delicate items such as the power supply or cooler in checked baggage. A desktop case is bulky and can be damaged even with fragile labels, so there’s no guarantee the luggage will arrive safely.
I’d avoid putting the expensive or fragile components in checked luggage. Baggage can be lost, crushed, or opened. GPU, RAM, motherboard, storage drives, and possibly the CPU are better protected in carry-on luggage if the airline’s size and security rules allow it. Pack each part in an antistatic bag with firm padding.

That makes sense. I’ll check the airline’s carry-on limits and look up the destination’s temporary-import requirements before traveling.
