The 10 Worst PCs of All Time

Consumers who purchased this machine entered a new dimension all right, the altered dimension of Dell Hell. The Dimension 4600 was only a middling machine when new, but after about a year--or shortly after the standard warranty expired--power supplies in some machines began to fail. Worse, Dell's customer support misdiagnosed some of these problems as motherboard failures.

Dell's support forums filled up with complaints from similarly powerless users, but the company refused to admit to defects with the power supply. (Dell politely declined to comment for this article.) The Dimension 4600's problems were yet one more reason why the "Dude, You've Got a Dell" tagline became a joke--though not a particularly amusing one for some customers.
