The Dell Optiplex 390 is a business-oriented desktop computer from 2011. Dell had a couple of configurations that could be bought originally. Either an Intel Core i3-2120 or a Core i5-2400 could be chosen from for the processor. For the operating system, it was either Windows 7 Home Premium, Professional, or Ultimate. Up to 8 GB of DDR3 memory could be installed, Intel HD Graphics, a 512 MB AMD Radeon HD 6350, or a 1 GB AMD Radeon HD 6450 could be chosen from too.
I bought this Optiplex 390 for $50 from the Arizona State University Surplus Store in January of 2020. This meant it was my main desktop computer for a short time before I replaced it with my own custom built PC.
Originally, this computer would've shipped with Windows 7 as previously mentioned. Since Dell still hosts recovery media for their Windows 7 and newer computers, it was easy to reinstall the OEM Windows installation. That's what I did when I first got the computer. I eventually upgraded it to Windows 10 since Windows 7 support ended on January 14, 2020. Now, this Optiplex still runs Windows 10 and is a part of my home Active Directory network.
I've done some upgrades to this PC over time. Originally, this PC came with a hard drive and no dedicated graphics card. Therefore, I ended up buying an AMD Radeon HD 7470 first to use as a dedicated graphics card. Since then, it's been replaced with a NVIDIA GeForce GT 710 that I randomly picked up at Best Buy one day for some reason. The Radeon HD 7470 now lives in my HP Compaq Prodesk 4000. The original hard drive has also been replaced with a SSD so that Windows 10 runs well.
