To address some of the other comments: the system looked pristine... BUT it was open BECAUSE WE PAID THIS COMPANY $125 / hr to set up the computer and have it ready for us.
I think we got taken, personally.
Yeah considering what it takes to 'set up' and iMac out of the box, I'd say you got taken.
Remove from box, remove packing cover, batteries in keyboard and trackpad/mouse, plug it in, turn it on and follow the onscreen prompts.
Of course if you bought other software along with it and they had to install that, maybe I could see a small fee.
