I bought one of these several years ago, and then bought another because I like the first one so much.  They both arrived in very close to like-new condition, with newly installed 2 TB hard drives.They are very nice machines that can do lots of things like run Office 365 or an open source equivalent, but you need to understand that these are refurbished business computers, and therefore have some limitations--or maybe I should just say that they are a bit different than a home PC, but can be easily set up for a nice homework machine.  It is NOT a state-of-the-art gaming platform, and doesn't pretend to be one!1.  As a former business machine, it was meant to connect to an Ethernet LAN, so there is no Wi-Fi inside.  You can easily fix that by adding a very inexpensive Wi-Fi USB dongle-type adapter for just a few dollars.  In my case, I really wanted Ethernet only, so I'm very happy with what I got, and maybe saved a few dollars by not paying for something I didn't need.2.  Again, as a business computer, you get two display port connectors.  The nice part about this is that you can have two monitors running in Windows.  Good for a business environment, but you may not need both.  If you just want to hook up an older monitor you already have at home, you can buy either a display port-to HDMI cable here on Amazon, or just a simple DP-to-HDMI adapter for under $10.  If you have a decent monitor at home already, it may have a built-in Display Port connector.  Display Port and HDMI connectors are easily confused at a glance, so it wouldn't hurt to check.3.  The computer comes with Windows 10 Pro--ideal for most of us.  The Pro version has a few more networking and remote-control features that I really wanted, but maybe you don't.  I see it as a bonus, for the price, and most people may not know or care whether it's the Home or Pro version.The two machines I bought, like many of them that are a bit older, can not be upgraded to Windows 11.  Some might say that's a blessing (!), but it also means that they will be good for only a few more years until Microsoft forces all of us off of Windows 10.  That's a Microsoft issue, not the fault of this particular computer model.I have two other computers besides these two that I bought or built, and they can't be upgraded either.  BUT LOOK AT THE PRICE YOU ARE PAYING HERE FOR SUCH A DECENT COMPUTER!  It's a great deal, and will be a solid performer for several more years...then maybe you can come back and buy something equally cheap a bit later--or for some of us, these computers can be turned into a very nice Linux desktop system.  Remember that there are still lots of people out there using Windows 7 PCs to this day, so you'll be ahead of them, so to speak.So there you go--caveat emptor.  Read the description, understand why it is available for such a low price, and buy accordingly.  You're not buying junk.  These are very decent, but used, and refurbished.  I'm very happy with my two well-built, solid, computers from this vendor.  They've done a very nice job with them, and I'm very satisfied with what they sold me!
