Used Dell Optiplex 7010 ultra-small form-factor desktop computer. Has an i5-3550S processor, quad core 3.0GHz. Has 4GB RAM, 750GB hard drive (non-SSD), Windows 10 Home, DVD-ROM. Works great. Please note, these ultra-small form-factor models do not have wireless networking built-in, so you will have to provide a Wi-Fi adapter if you plan to put it on a wireless network. Also note that the photos show a similar model I'm also selling that has an i3 processor. Rest assured that this listing is for an i5 processor model. I can provide specific photos of this one if need be. I also have a couple 7010s with i3 processors and 320GB hard drives for $30 less each. Please don't bother asking me if this computer is available. If it is still listed, it is still available. I will not reply if you just ask if it is available.
