Buying a Dell R640 from IT Server Exchange
Every unit is tested before it ships and its condition is stated up front. Build one to your own specification in the configurator — processors, memory, drives, controllers, network cards and rails are matched to this chassis, so the parts offered are the ones that fit — then send the configuration over and we'll quote it.
