Hey guys, I am going back to Canada in a week or so but I am bringing a Antec H600 Cooler, i7 4770k and a Gigabyte Z87 mobo from China. All of them are in their boxes but I already put the CPU itself onto the mobo. Should I carry the parts in my backpack onto the plane or should I put it for luggage? Will the customs let it through since the coolers already got liquid in it. The Chinese customs are pretty tough this year also.
