Which method should I use to ship my computer overseas?

I am moving from the east coast to London. I have an Apple desktop computer and I can ship it in the original packaging. Which method would be safest, but not too expensive?|||Fed Ex may be able to help you out. Not too pricey either.|||FedEx|||Really, any of the big three will be able to ship your package: DHL, UPS, or FedEx. Just don't trust it to the US Postal Service!
