And I haven't seen any Dell computers with AMD processors.
Nor will you. Dell has announced that it won't be using AMD CPUs for next good while. Intel offers them too many "incentives" to stay strictly with them.
Dell observes the rule of: How little can I do and get by with it. Cheap RAM. Cheap motherboards. Celeron CPUs. PSUs that are bare minimum for what came in the box, with no overhead for expansion. Proprietory parts that have to be replaced by Dell parts, which are extremely overpriced.
Forget calling their customer support. One in five calls gets a native English speaker, if you're lucky. And with a Dell, you will definately have to speak with someone as their comps don't stand up like they used to.
Chankama is dead on about warranties as well. If you open it up, you void the warranty. Which means you have to use Dell's channels, which may or may not get it done within a reasonable timeframe. Which may or may not fix the problem the first, second, or third time.
Besides, if you want someone else to build it with decent parts, look elsewhere online. Try
