I know for a fact that the two computer makers Prole and I mentioned will ship you a pre-built box with an empty hard drive and no OS. So you can actually build a Linux machine and not pay the Microsoft tax, and isn't that nice? Or if you already have a license for a MS OS, you don't have to pay all over again.

Dell is notorious for putting shovelware on their PCs. Best advice I've heard is that if you get stuck with a Dell, wipe the drive and start over. To quote Ripley, "It's the only way to be sure."
