Lots of USB ports in front and back. Quiet. Good DVD burner. Fast (nice processor - Intel i7 2.80 GHz). Runs well with Windows 7.
We have been using these computers for 6 months. Power button stuck on most of the sixteen computers we ordered, causing them to reboot constantly. RAM died after only 4 months of use on one computer. Another computer will not boot up properly.
The Dell OptiPlex 980 computer is hit-and-miss as far as quality goes. Out of sixteen computers, we have had minor hardware issues with over half of the computers (power button sticking), and major hardware issues (useless RAM/will not boot up properly) with two computers.
