i had my computer shipped to me from texas to korea.
luckily i boxed it in its original box, they sent it single boxed, and i couldnt ask them to remove the heatsink.
arrived in one piece, just had to reseat the RAM and it worked 100%.
carrier was fedex international saver or whatever, it was the cheapest one
luckily, my heatsink was a 3 lug one. (thermalright AX-7) with athlon 2200
