DELL Optiplex 7020 Tower Core i7-4770 3.4GHz 32GB 1TB + 240GB SSD DVD-RW Wi-Fi Win 10 Pro (Renewed): Pleased at first because the computer was fast and quiet. However, less than 12 months later it began overheating. Now it won't boot at all and the power button flashes a code that indicates a bad motherboard. It's a shame because I did like this while it lastedSalvaged the storage and DVD drives and other peripherals to use with other devices, so not a total loss. May even end up using the case to build my own computer.
