How long does Dell usually take to construct a laptop?

Just curious as to he average build time for a laptop from dell. I purchased an Alienware m15x on 5/23 and I upgraded only the processor to an i5 and the hard drive to 500 GB and the personalized nameplate. The estimated shipping date (not delivery date) is 6/7. Now to me that seems to be a very long time for such minimal upgrades. Any thoughts or comment from first-hand or third party experience? Thanks!|||I ordered mine with 6g ram 1333z, i7 processer, 500gb, 9-cell battery, and more. i ordered mine on the 20th... and the est delivery date is june 7th.. There won't be much of a difference :)
