Last summer, as part of my job, I purchased 30 of these computers to equip an elementary school computer lab. This model of computer is not "top of the line" but they have served our students extremely well during this school year. These computers are used each day - ALL day - by approximately 400 students in grades two, three and four. The computers have withstood the unavoidable, minor abuse that comes with the volume and age of students that work on them each day.
We have had one machine experience a failed hard drive but a Dell technician came out the next day to replace the hard drive and repair this system.
If you are in the market for a basic, hardworking, desktop computer, consider the Dell Optiplex line.
