Used Dell Computer Windows 7 Professional

(4 reviews) Write a Review

Good things come in small packages, and this small form factor PC is the proof! The Dell OptiPlex 780 SFF may take less space, but it offers just as much power. It measures less than 4" wide, 12" tall, and 13" deep.

One Year Parts & Labor Warranty Yes it is strange to see a warranty that long on something used or refurbished and even stranger to see it coming from a retailer rather than a manufacturer but that is what separates us from the crowd of computer retailers.

    So far, impressive. Very good.

    My computer was old and finally broke down. I didn't want to spend the $$ for a new one, and I wanted to keep windows 7 (I tried windows 10 and didn't like it). Discount had the option to pick windows 7, and the price was really good. It's my first purchase from them and not all reviews were good, so I was concerned making the purchase. But I also didn't have many options going used, so I took the chance. I've had it for a couple months now and so far I could not be happier.. It works beautifully, no hidden charges, no surprises. If it lasts at least a couple years, I will be ecstatic. Very Happy.
