Gotta reiterate . . . Dell (and others) get a bad rap. They make good PCs that are as idiot-proof as they can be made, and are often exactly what they should be for the price, especially at the low end.
If a "stranger" asked me to build a PC for him, I'd probably do it for free. But 2 days later when he calls with some fool question, after 5 minutes I'd tell him to call the Geek Squad and change my telephone number. (I help out here because you guys don't have my phone number
Dell et al doesn't do that. So the PCs can cost a bit more than self-built, and don't allow you to screw with them too much. That's the trade-off.
