This PC is quite an engineering feat! Tiny but powerful as all get-out! OptiPlexes are built with higher quality components than you'll find in typical off the shelf retail models. These are perfect for business or home! The Dell OptiPlex 990 comes fully loaded with blazing speeds supported by a power Intel Core i5 processor and 8GB DDR3 RAM, with choice to upgrade to 16GB. With a reliable 128GB SSD Drive, you will have plenty of room to store your favorite videos, photos and anything else you need. A fresh installation of Windows 10 PRO will be added, included with a new license. This computer is refurbished, Grade B showing minor cosmetic signs of wear that do not affect functionality.
