Frequently Asked Questions
1. What motherboard is in a Dell Optiplex 780?
It depends if you have a mini-tower, small form, or ultra-small form factor unit because they all use slight variations of the Intel Core 2 motherboard. All units we carry use Intel processors. Some have Core 2 Duo (E8400), Core 2 Duo (E7500) 2.93GHz, Core 2 Quad (Q8400) 2.66GHz, Core 2 Duo (E7500) 2.93GHz, Core 2 Duo (E8400) 3.0GHz, Pentium (E5800) 3.2GHz, Core 2 Quad (Q9400) 2.66GHz, and Core 2 Duo E7600 3.06GHz. You can browse the products above for more information. With our refurbished units, we take special care to restore them back to working order. All defective parts are repaired or replaced, and each unit undergoes a strict quality check process to ensure that it gets to you in good condition. Feel free to customize the system unit by choosing whether or not you want an operating system, memory, primary storage drive, and even warranty. All operating systems will be pre-loaded on the PC, and device drivers that are necessary will be installed. We can also include additional items like peripherals such as mouse, keyboard, and speakers.
2. Are refurbished computers long-lasting?
Yes, they are. Over the years, there have been preconceived myths surrounding refurbished computers. Most people who believe these tend to think that reconditioned laptops and PCs are unreliable, slow, and will run poorly. While these computers are used, they are rehabilitated with care because defective parts are either repaired or replaced entirely. Some people think these computers are used, sent back, and then resold again. It's far from true. Most refurbished machines were working fine before they were sent back. Some of the reasons why companies send back computers are due to upgrades or exchanges. As long as you buy your unit from a legitimate refurbishing outlet, you can expect quality computers on par with fresh-from-the-box systems. Before they are resold, refurbished computers go through several computer technicians and experts who will see to it that the unit is working as it should be. They put them through several quality tests to ensure clients going home with these units will be happy.
