Good things come in small packages. This PC is an engineering miracle. The Dell OptiPlex 780 USFF powerhouse weighs in at just 7 pounds and has a built in power supply. It measures less than 9.5" tall, 2.6" wide and 9.75" deep.

It's no wonder these are sought after PCs in the Point of Sale world. You can't by a more powerful, smaller computer. This particular OptiPlex 780 USFF sold for over a thousand bucks. It has a Core 2 Duo processor just shy of 3ghz and comes standard with a 160GB hard drive

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.

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.


  • Intel Core 2 Duo 2.93Ghz CPU
  • 4GB DDR3 Memory (Or Upgrade to 8GB or 16GB)
  • 160GB SATA Drive (Choose any size you want)
  • Integrated 10/100/1000 Network Card (NIC)
  • USB 2.0
  • Integrated Video
  • Integrated Audio (AC97)
  • 1 Serial Port
  • Windows 7 Pro Pre-installed (Or Upgrade to Windows 10)
  • Includes pre-installed Recovery Partition.
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.

    Product, Shipping, Support

    Product received in great condition and working order as advertised. Packaging was excellent. Supports responses to my questions was excellent. Only improvements I can recommend is, 1.) List whether OS is 32 or 64bit, 2.) Although there were instructions about activating OS I had trouble locating OS key. Contacted support and they sent a picture where key was located. Including picture with instructions would help greatly. Sometime a picture is worth a thousand words. Thank You Discount Electronics and a special Thank You goes out to Joe for responding quickly to my questions.

    Reliable, space saving workstation

    We've got four of these USFF systems deployed here in the work place, and have never had issues with any of them. Fast and reliable, with quick and easy setup. We prefer OpenOffice to the Libre Office package that comes pre-installed from Discount, but they are not loaded with bloatware or unneeded apps, just Windows XP Pro and an office suite. The one year warranty on a pre-owned system gives us peace of mind, even though we've purchased about 10 total systems of various flavors from Discount over the last six or so years and have not had a defect.

    I have not had a chance to use it much but so far everything seems GO a okay. I have bought a total of three from Discount Electronics and all have performed great. I did have to send the laptop back to your company for warranty work and they responded very fast. In fact it must have had a problem as they send a replacement laptop to me.

    I am a very satisfied customer

    A great update if you are looking for a new system. Working in digital media and constantly using the Adobe suite is now a breeze compared to my old system - although I did upgrade the memory & hard drive. It's fast, quiet, and small so I now have more room on my desk for other projects. Great buy, five stars all the way.
