I'm traveling from Canada to my home country for a few months and want to bring my desktop PC components with me instead of paying the high cost of shipping. I would pack the motherboard, RAM, CPU cooler, power supply, graphics card, case fans, keyboard, mouse, and other peripherals in my luggage, then assemble everything in a PC case I already have at home. I won't be bringing a monitor or the case itself. Could customs charge import duties on these parts, even though they're used personal belongings, and are there any declaration or packing issues I should know about?

One practical approach is to leave the case behind and buy or use a case at your destination. Bring the valuable core components as carry-on items and check only sturdier, cheaper parts such as the power supply or cooler. If you do check anything, use a rigid box with plenty of cushioning rather than trusting a suitcase alone. Also verify airline weight and size limits before packing.
Customs rules depend on the destination country and whether the items are considered temporary personal effects or goods being imported permanently. Used parts without their original packaging may look less like new purchases, but that doesn’t automatically exempt them from duty. Keep receipts or other proof of ownership, check the destination’s personal allowance and temporary-import rules, and declare them if required. Don’t rely on hiding the packaging to avoid fees.
I’d avoid checking the expensive or fragile parts. Baggage can be lost, mishandled, or stolen, so the GPU, RAM, motherboard, storage drives, and especially any drives containing personal data are safer in carry-on luggage if the airline allows it. Remove heavy internal parts from the case and protect them individually with anti-static packaging and padding.
