Update:Wow. Yeah, I left a review right after getting it, and thank goodness I waited before handing it to my father-in-law. In died the next day (after this review) and they said the only thing I could do is return it, which kind of makes sense. But regardless, it wouldn’t turn on. A Google search said I had to try disconnecting all peripherals, I did that, nothing worked.All in all, it was neat that it came with a wifi USB in the box, but it nothing about this pc is worth more than 1 star unfortunately.Original:Reviewing for: Dell Optiplex 3020 SFF Desktop PC - Intel Core i5-4570 3.2GHz 8GB 500GB DVDRW Windows 10 Professional (Renewed)Product specs are at the end of this review.I got this for my father in law who had his old PC break down. Honestly, I was a little surprised at how well it looked for an older used computer, but there was definitely some signs of use. That being said, first thing is the price. I mean, it's less than $200 regular at the time of my purchase (it was on sale for my purchase), so it's nothing too crazy expensive.Next, this PC isn't good enough to play hardcore games on, but for a general office computer, perfect. The motherboard can run up to 16GB of DDR3 RAM, which is what most would only need anyways (it's what my rig has), so that's great to know. I wouldn't be putting money into the new RAM myself, but it is an option.You can also add 2 back panels for addition things like a wireless card, USB-C ports, and so on.Lastly, it comes with Windows 10. You should know, you can NOT install Windows 11 out of the box (more on that later). However, it has Windows 10 Pro, and that should be fine for the majority of users anyways. Windows has already announced that Windows 10 support (updates) will continue until October 14, 2025, so there's lots of time to worry about updating down the road.Okay, enough of the pros, what about the cons...First, I'm unsure why I can't find the windows key using typical CMD or Powershell queries. Additionally, windows defend wasn't installed, so make sure to download that if yours doesn't come with it. It seems to give me problems with I try to download it, so I'm unsure what's going on, but I'll move on. Windows does show it having a Windows 10 Pro activation, but I'd like to transfer things over to my SSD. Maybe an OEM license?Those looking for Windows 11? You won't get it with this PC. This has TPM 1.2, and Windows 11 requires TPM 2.0 or higher. This is a physical piece of hardware that can be difficult to find to ensure it fits the motherboard, but I'm not even sure this motherboard can take TPM 2.0. Alternatively, you can get a CPU that has fTPM, but I also don't think this motherboard would support that high end of a CPU.Lastly, I would highly recommend you upgrade the storage. By a cheap SSD (you can get a 240GB one for ~$40 CAD), reinstall Windows on that drive, then use the storage that came with the PC as a second drive. I personally always recommend this because the speed of an SSD is light years faster than an HDD. Although Windows isn't incredibly slow, it is slower than I'm used to on my internal SSD.PRODUCT SPECS== Basics (What comes with this) ==CPU: Intel i5-4570 @ 3.20 GHz, quad coreRAM: 2 x 4GB 1600MHz, DDR3 single channel RAMGPU: Intel HD Graphics 4600Trust Platform Module 1.2 - Therefore, it does NOT support Windows 11 (TPM 2.0 or higher required)Storage: Western Digital 500GB HDD - Model WD5000AZLX, 7200 RPMOne corded keyboard (it's okay I guess)One corded mouse (I'd recommend upgrading)== End ==== Motherboard ==This is a Dell 0WMJ54 motherboard, which is a Micro-ATX form.
