This elderly PC (build date 2012) is very clean and well maintained.  It is clearly a business grade computer that has sat in an air conditioned and air filtered computer room. The interior is clean and dust free, and the exterior looks brand new.  Build quality is excellent.  It came with Windows 10 pro installed, which will be dead in about a year and a half. (Late 2025)I can't give it 5 stars because of the abysmal wireless dongle that came with it, and the inability to add more RAM or upgrade the graphics card.As a device designed for working as a server or other commercial system support, it has only basic graphics capability, and no provision for wireless connectivity or Bluetooth.  As a result, wireless/Bluetooth capability must be added via those little USB dongles.  It came with a 'no-name' wireless dongle that couldn't maintain connectivity in a room that is separated from the router by a single interior wall.  Fortunately, I already had a NetGear dongle of an older design that works well.  So the purchaser should probably budget for buying a higher quality dongle at some point.  No Bluetooth dongle was included.The SSD is a 128 GB Lite-On card, an OK but cheaper SSD, added as an upgrade before resale.  It isn't the largest SSD you can buy, but it is adequate for most Linux set-ups. As a Windows machine, you will need to use an external drive with some reasonably sized storage capacity.I have installed Linux Mint v21.3 on it, and it is fast and responsive.  The limited graphics capability and 8GB limit on RAM makes it unsuitable for "Serious" photo or video editing but for most home uses it is fine.  As a secondary PC, it is also useful.I intend to use this as a learning and test platform.  Since I paid WELL under $100 US for it,  I intend to treat it badly and without fear of damage to the machine itself or to the Linux OS.  It hasn't cost me that much money, and if I really mess things up, I'll just buy another.  Learning more about Linux is my goal.  I'd buy it again, but I might spend a bit more and get one with a bigger SSD.
