Get an evaluation PC (or one of the first in the rollout) pre-imaged by DELL. Image this PC, boot to PE/Acronis/Ghost and create your own image. Don't allow the DELL image to commence the install procedure.
CONS: you won't be able to alter the image, ie add upgrades or new software to the image, unless you have a method of bringing the PC back to a Pre-System image ie: like a fresh PC from DELL.
