Worked great for 2 days, then nothing. Called Dell and they said it sounded like a fried mother board. I would have to send the computer to Texas for repair. They were sending a shipping box and label. 4 weeks later, no box no label.

This PC was bought for basic web browsing/email purposes and it has been working great and trouble-free for close to a year now. It is plenty fast enough and has enough memory for basic browsing needs. Keyboard and mouse are comfortable to use. Great value and I have no complaints.

Had a Dell prior to this one and it plugged along for seven years. Hoping for a similar life span. Very little bloatware on it at all, which is nice. Small footprint on the desk.

I bought this to replace some PCs at work. It's a great PC. Good performance, plenty of RAM, simple set up. Normal Dell bloatware,... otherwise a perfect plug and play replacement.

This turned out to be a great computer for the money. I am very satisfied with the power as I do a lot of computer graphics and have had no problems running Adobe Illustrator and Photoshop at the same time.

The computer works very fast, which was what we were looking for in the first place.

2nd time is a charm, I returned the one with a subpar graphics card and received the one with the correct graphics card and it is awesome!

So for much doing everything I expected

When my seven-year-old Dell computer failed, I turned back to Dell to replace it. But on the Dell site no computer was configured to my mental specifications. Moreover, if I had customized a computer, and even then not the way I wanted it, it wouldn't have arrived for some time.
