This is a refurbished Dell Optiplex 990 SFF desktop offers great performance in a compact case, making it a great low-cost computing solution! This business class Dell PC originally sold for over a thousand bucks. You save 85%. 

The Dell OptiPlex 990 Small Form Factor measures less than 12" tall, 4" wide and 13" deep. If space is a limitation, this is what you need. This computer can easily nestle behind a monitor and it's light enough to be moved around the office easily.

Upgrade? Go Ahead. Take a look in the upper right. You can add memory, a bigger hard drive, WiFi and more. But here's the best part. You can custom configure your PC and still have it shipped the same day. That's right. We are THAT good.

Warranty? You bet. This machine, like every other computer we sell, comes with a One Year Warranty direct from us. The other guys charge you 50 bucks or more for a third party warranty. There is a BIG difference between our direct warranty and the warranty the other guys sell you. We stand behind our products. We have telephone support and cover all parts and labor. Anyone who has had the misfortune of a big box third party extended warranty knows how little they really cover and how hard it is to get anything done.

Discount Electronics has the lowest prices for refurbished Dell computers on or off the web. When you are buying from Discount Electronics you are buying direct. This means you save money and know who to contact when you need help. Market places like Amazon and NewEgg add additional costs to the sale that, ultimately you pay for. These market places also make warranties a problem. You aren't really buying from NewEgg or Amazon and when you need help it is difficult to figure out who you really did buy your computer from. Contacting them can be nearly impossible.

Attention: After January 14, 2020, Microsoft will no longer provide security updates or support for PCs running Windows 7. Now is the time to upgrade to Windows 10. If you continue to use Windows 7 after support has ended, your PC will still work, but it may become more vulnerable to security risks and viruses. Your PC will continue to start and run, but Microsoft will no longer provide the following support for your business (No technical support, no software updates and no security updates). We recommend upgrading to Windows 10.

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. Service after the sale and our warranty is what this company is all about.

    So far it is fine, but box was damaged in shipping. Computer was well bubble wrapped so no visible damage. Selling Co was great.
