Own a Dell Precision M4700 workstation (absolute beast of a laptop, i7 3840QM, 32GB RAM, 2X 256GB SSD), and 2 R610 1U rack servers in colo. I've been buying Dell servers since 2005, never a problem, completely satisfied.
Their high end consumer, and mid-to-high-range server gear is pure quality, at decent pricing to boot (if you can work a deal with sales rep., or find a decent unit on Dell Outlet that is).
Having worked in a place using only their top-line products (laptops,workstations and servers) since 2001, I can't stress how true this is. That stuff is pure quality. Quite a lot of the machines that were bought in 2001-2003 are still there, up and running (of course with second or third batch of new hard disks). Those that are not there anymore were abandoned because they became too slow for current standards, not because they broke. Which basically means we're not sure of the actual lifetime yet since there hasn't been any of the machines that just didn't work anymore.
Also extremely important: Dell obviously did quite some research in figuring out which components work together well. This translates in close to zero OS problems due to hardware goining nuts. In other words: no kernel panics, no blue screens. Some people hardly belive this, but the only time I saw blue screens/kernel panics in the past ten years was when doing stupid stuff myself, never because of the machine.
(note: I cannot compare to other brands here, maybe they are as good as well - I certainly hope so for their users)
