My experience with the likes of Dell is that they'll deliver it but they won't support it.

Sure, there's a support contract. And they try. But while they sell a box that says Dell, the innards are a hodgepodge of stuff from other places. So when certain firmware doesn't work with something else, they actually can't help because they don't own it, they're just a reseller.
