DELL Desktop PC OPTIPLEX 7020 Core i5-4590 Specifications: ・Manufacturer: DELL ・Series: OPTIPLEX ・Model Number: 7020 ・CPU: Intel Core i5-4590 @ 3.30GHz ・Memory: 8GB (DDR3 4GB x 2) ・Storage: WD HDD 500GB ・OS: None (If requested, we can install and ship with Windows 7 32bit / 64bit or Windows 10 64bit) A Windows 10 product key sticker is affixed over the Windows 7 product key sticker on the top of the unit, making Windows 7 license activation difficult. Windows 10 license activation should be easy. (I used Windows 7 for a few days before listing this item) CPU thermal paste has been reapplied. Please note that I have a cat at home, but I do not smoke. Also, the color may appear different depending on your viewing environment, so please be aware of this. I cannot respond to requests for price reductions, but the price may be gradually reduced over time.
