Hi, I want to purchase a new BTO 2.8 or 3.06 Imac. Changes like HDD upgrade wireless mouse/keyboard. I am going on vacation the 26th of July for three weeks and I'll be able to order it Friday the 11th or Saturday the 12th of July. I really want to have it before I go on holiday. So, How long will it take for a Imac to ship from the day it's ordered. Thanks! P.S. I live in The Netherlands, I don't know if it makes much of a difference with the US, not for the UK I think.
