Re: comparison between HP & DELL
For starters, after the Compaq deal, HP acquired the DEC server patents along with the tech Compaq developed. Those with the developments made by HP seem better than the Dell standards.
As far as the EU units, most (if not all) commercial grade HP units are bullet proof. Research the issues with the Dell Optiplex units and make your own conclusions.
As a tech certified by both Dell and HP and providing tech support on both, neither seemed to have a real edge but the HP system boards seemed to be more dependable.
Perhaps you can find some independent stats of MTBF on units. If I were an IT manager looking at a major investment I would not "Ask the Barber if I needed a hair cut."

Good luck!
